I installed Ubuntu alongside Windows 8, however have decided to unisntall Ubuntu.
First I booted into Parted Magic and, using GParted deleted all the ext4 and swap partitions.
This leaves me with the same partitions I had before I installed Ubuntu:
/dev/sda1 ntfs WINRE_DRV /dev/sda2 fat32 SYSTEM_DRV (my UEFI partition) /dev/sda3 fat32 LRS_ESP /dev/sda4 unknown Microsoft Reserved Partition /dev/sda5 ntfs Windows8_OS /dev/sda6 ntfs LENOVO /dev/sda7 ntfs PBR_DRV
I expected deleting the partitions would be enough to remove Ubuntu and allow me to boot back into Windows 8, however whenever I boot I get the following error:
error: no such partition.
which is followed by GRUB rescue:
In my UEFI partition, there are two directories
BOOT is a single file –
boot.sdi. In the
EFI directory are another two directories,
BOOT are two files,
Microsoft directory has a directory in it named
Boot. Inside it are the normal Microsoft EFI files (as far as I can tell).
Thinking there were still GRUB files left, I ran
find . -iname "*grb*" and
find . -iname "*grub*" in the UEFI partition, however only found one empty file,
bootx64.efi.grb (which I deleted).
How is GRUB still installed, and how can I uninstall it?
I'm pretty new to UEFI and so things may need explained in detail. The computer is a Lenovo IdeaPad Z580.
edit: I forgot to mention, I deleted the
ubuntu folder in the UEFI partition.
edit 2: I managed to get back into Windows through a "System Recovery" option in the laptop's BIOS settings. This may or may not have solved the issue.
edit 3: okay, I can boot almost normally now. When I boot, I see
No partition active for a couple of seconds then Windows boots. How can I remove that?
