Installation from USB stick problem
Tried:
- Tried: Disable Secure boot.
- Tried disable external graphics in UEFI. So the device can uses only integrated AMD Radeon graphics.
- Tried Select: Ubuntu (safe graphics).
- Tried run "Ubuntu (safe graphics)" with "nomodeset", but that parameter was already there.
- Tried USB disk on another device Dell and I can load Ubuntu without any problems so USB disk is fine.
- Tried Ubuntu 22.04.4 and it works.
- Windows fast start disabled.
Solution: Solved by load Ubuntu from another USB stick.
Windows 11 vs Grub and booting problem
I thought it was solved, but:
Ok, I could load Ubuntu from USB stick by Samsung. Kingston USB stick does not work. I do not why..
Next problem during installation. The Ubuntu installation wizard was automatically closed during the installation process...hmm, so I wait 20 minutes CPU and network was not active so I restart the laptop (because I do not know installation status).
Three restarts from Ubuntu to Ubuntu was without any problem. Then I restart to Windows 11 and then to Ubuntu and Ubuntu boot does not work: boot loop before show Ubuntu logo while starting... there is no error message (or I do not know how to display it.).
Run Ubuntu 6.8.0-35-generic (recovery mode) and run: dpkg and grub. Does not help. When I add run repair file system (fsck), I can load Ubuntu without any problem.
OK, some restarts from Ubuntu to Ubuntu are OK. Now I tested restart to Windows, It's OK, but when I try to restart from Windows, Grub is totally is missing and I can start only Windows.
OK, I followed the instructions: https://www.youtube.com/watch?v=EEfW_XJzhbI but still when I once boot to Windows then I cannot boot to Ubuntu.
Windows is causing problems!
Bypass solution: when you want to restart from Windows -> Ubuntu, loading Ubuntu always freezes. You have to shutdown Windows. Then turn on laptop and Ubuntu loads fine. It's probably related with -> https://superuser.com/questions/1830599/windows-11-keeps-messing-with-grub-at-every-restart-possible-solution?newreg=44e927a7d80143bcb5c773aaa37528ce
