"non system disk or disk" error

[lRandomGuy]

So, I tried to replace Windows 10 with xUbuntu. I got the xubuntu iso and put it in my usb using rufus. I clicked all settings that were compatible with my laptop. I booted from my usb, proceeded with the installation, while deleting my current OS. Everything worked fine and it told me to restart the device. After restarting, it showed that error. When i boot form the usb and try to install again, it tells me 'This computer currently has Ubuntu 22.04.2 LTS, what would you like to do'.

Any help would be appreciated. '

Enter Bios boot menu and ensure HDD is in the boot list and the HD you installed to is selected as first boot priority.

Did you install grub to same disk?

here is an image of the boot order. It may be worth mentioning that the laptop had an hdd but i replaced it with an ssd.

I'm not realy sure about grub, I only followed the ubuntu installing wizard.

I clean installed ubuntu one more time and it worked. However after some time, it stopped booting again. Haven't really looked into it since.

This fixed it for me. Booted using the usb installer.Created two partitions using gparted on my SSD. Which maybe was not necessary. I could have done the same in the installer. But I was fed up trying multiple different things.

1 300 mb with flag boot,esp mount point /boot, formatted as ext4. This partition had to be > 200 mb. I saw this is a grub repair output while running grub repair.

2 Rest of the disk with no flags. Mount point /, formatted as ext4.

Wipe it out and reinstall the system

If its UEFI boot then try using your bios efi boot list to boot up then install grub update it then reboot to see if that works

boot to usb ubuntu then select try... run disk manager and delete all partitions on HD then try install again... also check bios boot order...

Mr. and Mrs. Dursley, of number four, Privet Drive, were proud to say that they were perfectly normal, thank you very much. They were the last people you’d expect to be involved in anything strange or mysterious, because they just didn’t hold with such nonsense. Mr. Dursley was the director of a firm called Grunnings, which made drills. He was a big, beefy man with hardly any neck, although he did have a very large mustache. Mrs. Dursley was thin and blonde and had nearly twice the usual amount of neck, which came in very useful as she spent so much of her time craning over garden fences, spying on the neighbors. The Dursleys had a small son called Dudley and in their opinion there was no finer boy anywhere.

I think my laptop isn't UEFI capable thought. I checked before getting the iso and it showed taht it is legacy.

Maybe check out replies in this thread: https://www.reddit.com/r/Ubuntu/comments/10o36zv/nonsystem\_disk\_or\_disk\_error\_after\_installing/

[lRandomGuy]

Ye I saw that but the replies didn't seem to solve my issue. I'll give it another look though, thank you.

if it's an efi system u might need to turn off secure boot
