I've recently acquired the Pipo W3F tablet and after switching from Windows 8.1 to Android I wanted to go back to Windows.
I'm able to bring up the OS switcher but there is no Windows icon. Anyone know what is causing this and how to fix? Thanks.
Just a wild guess really, but this could relate too the file-system of the harddrive, unless im mistaken Android uses 'vfat' and 'yaffs2', and you prolly cant install windows on either of those.
That said, im not sure how you would overcome this (or how you even got it to dual boot, since looking at the PIPO site it doesnt do that out of the box) but you will prolly have to flash a firmware image thats windows only again.

I also got the tablet recently and ran into the same problem. There was no way for me to get back into Windows. I had to re-flash both Android and Windows. It wouldn't let me re-flash just Windows, I was getting an error saying it cannot create a "scratch" directory. I think when re-flashing Android it reset all the partitions. Once the Android OS was installed, the Windows flashed without any problem.
Good luck.

hello all..well tried loading winxp onto the extremely slow shift we all have been suckered into buying thinking it was a good thing..anywho
partitioned off part my c drive..fired up winxp..everything went ok..it went into its first restart and then i get an error "operating system not found" it doesnt give me the option at startup to select fista or xp just gives this error..
tried loading fista on using f3..still returned with the same error
so..what did i do wrong besides the obvious and buy one of these things !!
My god; what is this trend with asking for help while bashing the product you bought. I'm getting tired of this. Just do your homework, and buy product based on what you need, not what you read on forums, and sell your shift if you are unhappy.
On the technical side, XP cannot be installed after vista. It will not make a proper dual boot. And you might have fried your recovery partition in the process too.
If you don't have a bootable usb key, I suggest you to find an USB cd or DVD drive, and to use the xp setup from there.
Using a usb key, you can try to use bart's USB bootable CD at nu2.nu

I installed XP after Vista without any problems, leaving me with a working dual boot system. Simply repair the mbr using a Vista disc, then setup the dual boot menu using VistaBootPro.
Edit - If you don't have access to a Vista CD, you can download the Vista Recovery Disc from various places - try here - http://neosmart.net/blog/2008/windows-vista-recovery-disc-download/
Yes, that what I mean in "XP cannot be installed after vista, it will not make a proper boot". Of course you can repair that situation with a boot cd.

Hi guys
I want to try the 8.1 update on my XPS 15, but I'm not sure if everything will work flawlessly.
Just in case something goes wrong, I want to switch back to 8.
So, is it possbile to "downgrade" using a system restore point (from Windows 8)?
Thanks!
Matt
no, that wont work. Try loading it into a virtual machine like vmware or virtual box instead assuming you have the full 8.1 iso
VM won't tell you much of anything useful. Even a relatively-low-level hypervisor still has some separation from the bare metal. I'd set up a dual-boot system. If you like 8.1, nuke the 8.0 install afterward.
i don't see any heavy downsides of 8.1... isn't there a recovery partition on your laptop, or a recovery DVD?
that way you could go back to 8
I have Lenovo Yoga 2 Tablet 10" with windows 8.1 (1051L)
its hard to use windows 8.1 on a tablet.
can i install Android on my tablet or even better ... dual boot with windows and android possible on this tablet?
it' fantastic. I have yoga 2 10 with android 1050L. It's very speed. but i think the problem is bootloader mods.
I think I would rath:cyclops:er run Android as the primary OS and the run Windows as a VM.

Successfully booted Android 4.4 R3 X86 from USB...
Hey all,
I have successfully managed to boot the 4.4 R3 efi img file from Android X86 on my 1051F. It's working pretty well, very smooth, but pretty much none of the hardware works (GPS, WIFI, Bluetooth, rotation, sound, etc).
Anyone have any idea how we could fix that? The process for getting it to boot is actually pretty easy. You download the img file from the android x86 site, use Rufus to create a bootable USB key (being sure to set it to GPT for EFI). You then need to disable secure boot on the tablet (instructions found various places on the net if you don't know how), shutdown the tablet, connect the USB key via OTG cable to the tablet, hold the volume up and power on. You will get into the NOVO menu. Once there, select boot menu and boot from the USB key (if it's not listed you probably didn't create the USB key in GPT, or it was detected when you powered on).
In order for it to boot into Android, you'll need a USB keyboard connected to select the android option. Alternately, you can just modify grub.cfg to set a default option and a timeout (which is what I did).
I'd really love it if anyone can provide some input on how to fix the missing drivers. Since the 1050 tablet is basically the identical hardware, I would think it should be easy to get the drivers over to this image, but I just don't know how.
Any help greatly appreciated!

I know it sounds basic, but have you tried getting the drivers from here: http://support.lenovo.com/us/en/products/tablets/yoga-series/yoga-tablet-2-1051
I wanted to do a fresh install of Windows 10 and I got the drivers from this place.

Thanks for the suggestion, but I'm pretty sure they only provide Windows drivers there. From my experience, Android drivers tend to need to be part of the image you install from, though I'm sure more advanced users could probably add drivers to a live install.
I'll take a look anyway, just to make sure, though.
EDIT: Just checked and, as I thought, only Windows 8 and 10 drivers. Realistically Lenovo don't support running Android on the 1051F, so it's pretty unlikely that they'd ever post drivers like that, unfortunately.

So after flashing the new lollipop update I found myself stuck in a bootloop unable to get into the android operating system at all. I used flashboot and the intel flash tool to try and restore to an older ROM. It forze at 91% with an "error:unable to mount /data" I then used the root tool to try and sideload and install the update.zip from adb shell. No luck. When I rebooted I got to a strange efi menu. Looked around, and it gives me the option to install with with windows?
Anyone have any ideas. I'm waiting for radio shack to open, its the only local place that sells USB otg cables locally.

That is something interesting. It is asking which os to boot to, not install.
I'd like to know how you got into the bios? I am looking for a way to install Linux....

Did you get this figured out?
I can see "fast boot" enabled. Have You tried to switch it off? any other menu is displayed?
Have You tried to "power+vol down" on it?
I've tried a few ways to get into the BIOS shown... all failed.
Maybe the only way to trigger the BIOS to show is to fully wipe/format the internal storage so the BIOS can't pick up droidboot or anything else. Quite risky though if it isn't the way.
I'm in no way telling anyone to do this and I have not tried it myself. I'd be curious to hear from any advanced users if they have ever completely wiped the internal memory and what options would be available to restore if things did go wrong.

This guy seems to have stumbled on it also. I flashed the stock kk firmware and I am trying to do it but can't get Lollipop update to work. But it won't boot after it fails so I am reflashing KK again.

Thanks for the link workdowg,
I'm still trying to work out how they did it. Could do with a step by step and whatever files needed uploaded and linked to. Also the bit about not using windows startup programs.

If you try it do let me know. I need to get into the bios to get started on a dual boot to Linux on this bad boy...
I will let you know.
I just asked for the OP to clarify a few things before I go ahead. I may try Linux first with Windows 8/10 being the final install.
So... conclusion. we have to damage firmware to boot efi...
If we could swap img file before upload to tab (during this 25 second wait) we could make windows installation possible. Am i right?

Thanks workdowg.
It seems it's not as clear cut as first thought. Mind you, I didn't expect it to be. I did try a HP keyboard with OTG in Android and that got picked up ok (No lights on keyboard)
I'm a bit in the same mind as Social-Design. I'd rather have a definite way to restore Android from a totally blank internal drive before I have a go. Just up to page 214 in the thread so it may be covered later.
UEFI soft brick?
Hi guys,
I accidentely tried to use the firmware on my 1050 as described in this thread. I can indeed load the UEFI BIOS with all its settings (even though most don't do anything). But unfortunately, I cannot load any OS. I always get the error "EFI Harddrive failed" - meaning it cannot boot fomr hardrive.
I have used an externally powered USB-HUB with mouse, keyboard and USB-Stick and connected to the 1050 via OTG-cable. If the stick is bootabnle with GPT x64 then it will boot from that stick. All 64bit windows versions that I tried failed to install with "ACPI_BIOS_ERROR". 32bit windows would not start, because the GPT is 32bit and the BIOS does not recognise it.
The best success I had so far was to copy a ISO from android-x86 on the usb stick. It will boot in live-mode from the USB. Not so suprisignly, mouse and keyboard are working, touch isn't. WiFI is working and the SD card is detected. I tried to install this version of android on the harddrive which works, but it installs the EFI GRUB bootloader which is not recognised by the BIOS.
I can also access the UEFI shell.
Unfortunately, I am running a bit out of ideas of what to do in order to get a normal system (or firmware) back. ADB-drivers obviously don't work (the Intel SoC driver is installed as well), so I cannot use the Phone Flash Tool.
Any ideas would be greatly appreciated.

You can get it to boot from USB? Get someone with to use tethered twrp and get a backup of the esp and fastboot partitions.
I have 2 things you can try if the goal is getting back to booting stock Android.

extract and dd this to a usb drive and see if it is able to boot it View attachment 3415895 if it successfully boots replace the fastboot.img thats on the thumbrive with one for your devices and see if it boots. if your fastboot.img is named droidboot.img rename it to fastboot.img.
If you can successfully get your devices droidboot/fastboot.img to load you can then disconnect the usb-otg cable and reconnect it to your PC and use the phone flash tools to restore your device completely.
My final goal is to install Linux desktop on a YB1-X90L android version.
I'm a linux guy but not familiar with android bootloader / storage. Can I assume that it's still a x86/x64 PC, and all stuff (bootloader etc) is storaged in normal disk?
(That means if I can boot into a normal Linux, there is a chance to dump everything or overwrite them with normal Linux installation.)
The biggest problem is that I cannot boot into a Linux liveusb: I can't find a place to change boot device order. It always starts with pre-installed linux even if a USB drive is attached.
Any idea will be welcome. :cyclops:
spoke to customer support on the same. The Bios for windows tablets and android ones are different. Windows tablets comes with secureboot and TPM built in. What you're looking for can be done on a windows tablet by switching off secureboot to boot from USB. But assured, the touch screen wont work, nor the bluetooth keyboard. Basically we're stuck with whatever OS the book is shipped with. Do not try to change it by yourself. Lenovo offers no support for such.
You could try this at your own risk.

configrmed working my eye
most computer past 2010 have tpm chips. They do more than secure boot and well, the boots not secure anyway. Things which are confirmed working have youtube videos and guides. They are also titled properly. I understand that the lenova book is also a cherry trail but seeing how there is no proof this works on a yoga book can we delete the guys conjecture about the tab3. Thats pretty ignorant. Out side of claiming some thing works that you obviously havn't tried, this android device comes with its own bios ( not legacy insyde) try china proprietary . Which is software fwi. It is what would be loaded on the efi partition for windows to manually load uefi boot menu off. They do not load off tpm chips, they are verified there. They load directly off your esp partition so without it, there is no way in hell you are getting dual boot to work via bios methods. Look into multi boot tassadar, compiling from source, doing research on not listening to that guy who just posts random links as if it means some thing. Your ability to re post others work does not make your smart. Get a job and stop misleading people
