[OS-Uninstaller] Safely remove Windows, Ubuntu... in 1 clic !

It is just an app running on Linux, not a full bootable system.

This now may not be current, but will still work.

This looks like a very useful tool, thanks.

I have W8.1, openSuse 13.1 and Ubuntu 13.10 on my laptop. I rarely use the first two OS and every time I update openSuse it messes up the boot process so that I can't boot into Ubuntu...

I propose to try OS-uninstaller to get rid of openSuse - do you forsee any problems? Do I have to run boot-repair afterwards? If it matters I have Secure Boot enabled on the laptop.

Thanks in advance.

I have not seen Yann around lately.

Have not seen may use Os_uninstaller so do not know details. It was more to install new grub or Windows into MBR somewhat like Boot-Repair. Not sure if it does any of the UEFI updates, but since some details are not obvious to a program, it may just be best to manually update. It also does not delete or reorganize partitions which you may want to do.

But have seen many use Boot-Repair with UEFI whether secure boot is on or not. But it is running chroots and grub installs. It does not delete partitions. Even grub does not modify UEFI boot order and it seems that Windows does modify UEFI boot order as it keeps becoming first on updates.

With UEFI every system has boot loaders in efi partition. Usually you have to manually delete folder with system you want to delete, and manually update UEFI NVRAM as it auto updates from efi folders. You also have to set default boot order in UEFI.

UEFI NVRAM boot entries are cached in the BCD store
BCD has 1:1 mappings for some UEFI global variables
Any time {fwbootmgr} is manipulated, NVRAM is automatically updated


# from live CD and use efibootmgr
sudo efibootmgr -v
The "-v" option displays all the entries so you can confirm you're deleting the right one, and then you use the combination of "-b ####" (to specify the entry) and "-B" (to delete it). Examples #5 is delete:

Thank you for your reply - food for thought there!
