My CPU broke and the CPU and motherboard were replaced on my DELL XPS 15 laptop. After this Xubuntu will not start. I need to somehow recover data in my home directory. GRUB is displaying and after I select Ubuntu, I get these error messages:

Dropping to a shell!

How can I recover the data in my home directory?

    Boot a live session and backup. Then reinstall. – GabrielaGarcia Jul 8 at 17:51
  • I do not see the disk when booting with live on usb – BERA Jul 8 at 17:52

    So that's the problem that prevents booting. Check UEFI setting as you may need to change the sata mode as you did when installed the first time. – GabrielaGarcia Jul 8 at 17:54
  • Ok! Yes i did, cant remember exactly what i did but i will try. Thank you – BERA Jul 8 at 17:55
  • You may have more than one problem. Are you able to boot into Recovery Mode from the GRUB menu? TPM may need to be disabled, along with Secure Boot and Fast Start, in your BIOS. /etc/fstab may need to be edited, as the UUID may have some extraneous characters in it. You may also wish to check that you've got the latest BIOS in the new motherboard. – heynnema Jul 8 at 18:02

I disabled secure boot (dont know if it made any difference) and changed SATA operation from RAID to AHCI in BIOS and xubuntu is starting again.
