Context in steps:
- Machine with Windows 11.
- Shrink Windows partition in 120 GB for Ubuntu 22.04.
- Boot to installation with USB.
- Make 3 partitions: | (1) 18 GB for root (/) | (2) 90 GB for /home | (3) rest for swap
- Continue with installation (install updates and 3rd party drivers was selected).
- Installation finishes and says "restart to use Ubuntu".
- "Remove USB drive and press enter" message with Ubuntu logo.
- PC reboots directly into Windows.
- Tried rebooting again and got directly into Windows.
- Windows Disk Management shows Ubuntu partition as "Not assigned"
I followed this steps in a VM in Windows and after installation the VM rebooted to GRUB. The only different thing is that I did not use the option "install 3rd party drivers".
