Wubi grub rescue after partition deletion

[Rylux]

Hi, everyone, I installed ubuntu 14.04(originally 12.04) with Wubi in addition to my Win 7, I had to use a boot rescue thing to being able to boot on both of them, and it worked fine. recently, i've deleted a small unallocated partiton, and integrated it to y main part, and I fall in grub rescue with the line unknown filesystem. I've tried many ways to fix it: with Super Grub disk (reuturned error 15) with boot rescue (here is the log: http://paste.ubuntu.com/7589009) and i'm still on grub rescue, i used "ls" on all my partition and it retruned "filesystem is unknown" each time. I have booted on a ubuntu secure live USB 13.04 and I saw that i can reinstalle grub on my main part. I wanted to know if this is the best solution, and if i will loose all my data( i've got a really important project i must acesss on my wubi disk) Can someone with more knowledge please help me?

Wubi is dead, it has always been more of a "try it out" gimmick back in the days when Ubuntu was completely unknown than a serious way to use Ubuntu. Ubuntu is not a Windows application and not meant to be installed inside Windows. Please do a real install by giving Ubuntu its own partition.

You have Windows booting in UEFI mode from a gpt partitioned drive.
But wubi does not work from a gpt partitioned drive. Because of that, the last supported version of wubi is 12.04. It is available it you want to install it but since it does not work easily on any new computer you are totally on your own.

And you now have grub installed in UEFI mode? Not sure how?
And you installed grub to sdb, which looks like your flash drive installer, which would have syslinux not grub in MBR. And you should grub legacy in the sdb drive?

Shows install with screen shots for both BIOS(purple) & UEFI(grub menu), so you know which you are using.

Also shows Windows 8 screens

Because you have Windows 7 you will not have any secure boot, or fast boot issues. But may have hibernation which should be off.

I don't undestand everything you said...
I don't know what sdb or grub leagcy is... if i thnk right MBR is the first part be read in the hard drive, right?
and when it worked, I was able to start Linux but not Windows directly, i had to boot a "Windows UEFI Loader" which loaded 7...

If you turn UEFI on or choose the UEFI Windows boot loader it still should work.
But wubi should not.

UEFI is turned on in my BIOS, I neverd changed it. I tried to start Win UEFI loader, and had grub rescue saying "No such device"

[oldfred]

Are you sure you are booting from sda, not the external drive which now seems to have grub?
You may have USB drive as first in boot order.
Or you should have a one time boot key, often f12 but varies by vendor to let you choose what to boot without going fully into UEFI/BIOS.

[Rylux]

I only boot on the key, i override boot at each start, i can't boot on sda, I get grub error

[oldfred]

Missed that you ran the 'buggy' UEFI fix from Boot-Repair. That replaces the Windows boot file with grub and renames Windows to be a bkp file.

/EFI/Microsoft/Boot/bkpbootmgfw.efi

You need to use Boot-Repair and undo the rename.


To undo & to rename files to their original names, you just need to tick the "Restore EFI backups" option of Boot-Repair.

Mmh this should put Windows UEFI loader working right? But he can't run my Wubi part...
