Re: [xubuntu-users] unable to install grub

Have you looked at the bios boot menu ? There may be something wrong there and you need to have it boot to usb drive  Sent from my iPhone On Feb 1, 2023, at 11:30 AM, Clarence Fender <leftystr...@gmail.com> wrote:  Yes, this is an install from a USB.

If your data is in a different partition, there should be no risk of deleting it (but always do a back up first). I have tried to repair a corrupted grub manually, but spent hours and did not succeed. At the end I decided to reinstall. Good luck. Michele  On Wed, 1 Feb 2023, 18:25 François P.

Typing "df", do you get something like /dev/nvme0n1p1    973952     6184    967768   1% /boot/efi (or perhaps /dev/sda1)?

Spent a long time researching: common problem going back years. Seems to revolve around boot, legacy vs new. I haven't touched any boot settings. Tried different partitions and flags. Tried using sda1 instead of sda - same error. sda   - all primary partitions 1M (appears by itself, no format) 500M  tried /BOOT and nothing 50G  ext4  / 16M swap remainder of space ext4 but not mounted sdb  ext4 /HOME Is there a different sda partitioning I need? No data on it so no worries. If I had hair, I'd be pulling it out. Thanks. -- François P.
