Was it a MBR or EFI install?

If it was a EFI install it may have shared the Windows Fat32 partition on your other drive.

 

If it's EFI

I am not sure how to access it in Windows, but you can boot a live disk and mount the Fat32 partition and delete anything referencing Grub or Ubuntu.

Then

  • efibootmgr
  • efibootmgr -b number_of_entry -B

 

*For example, num_of_entry = Boot0003 = 3

 

 

If its MBR, you can try the following. I am not familiar with Windows and this was pulled from a Microsoft KB.

Open cmd as administrator

  • Bootrec.exe /FixMbr

  • Bootrec.exe /FixBoot

I recently uninstalled ubuntu from my pc. It was located on the 2nd partition on my 2nd ssd (1st partition had mass storage for windows).

I have just deleted ubuntu from my pc by deleting its parition (yes, i know probably bad idea) because I don't want it anymore. However, I have noticed that the grub bootloader used to launch linux is still on my 2nd ssd.

 

How do I remove the grub bootloader on my second ssd without deleting the data I have on my first partition?

Format the partition in windows using Disk Management. It should be a 300MiB Fat32 partition. Ubuntu also should of had 3 partitions.

Fat32 for EFI, swap for swap, and probably ext4 for root.
