I'm running Zorin OS17 Pro on my dual boot machine. Last week zorin froze while opening an app. I restarted, logged in, and after a few seconds the desktop disappeared and everything froze. Restarted a couple more times and thenzorin won't fully load. Tried recovery mode on current and old versions and same problem.
Tried the live usb and the system check would get stuck at 11%. For the hell of it i tired booting windows 11 (haven't used it in months) and it would crash after loggon on. Changed the cmos battery and now the live usb boots but my zorin install is giving me the same error. Boot repair fails too.
When you logged into Windows, did it have prompt to run any updates? It's possible that this caused some changes in the BIOS and messed with the bootloader. Also, are you able to boot again into Windows at this time?
And, while booting into the live USB drive are you able to run efibootmgr manually from the terminal?
I would also suggest checking out this thread. Unfortunately, not two cases seem to be the same when it comes to this type of errors, and it's tough to point to one particular issue:
No i did not update windows. Yes efibootmgr loads in the terminal on the live usb. Before I replaced the cmos battery the live usb wouldn't fully boot either.
Do you have Windows update automatically? If so it could be that KB5041585 is installed, and if so will prevent any GNU/Linux from booting, even a live .iso as it won't have a valid EFI shim. Interestingly on my youngest's machine on shutting down, the choice unusually offered two options, shut down and install updates or just shut down. I chose the latter.
KB5041585 is not installed. I Windows hasn't been updated in a while. Tried running boot repair from the live 17.1 and I got a message talking about enabling a repository for grub-efi. Software store doesn't have this so I presume there is a terminal command for this one. I was able to access my saved files on my zorin partition and back them up in case I have to reinstall with the new 17.2 iso.
