I had a working Ubuntu 12.04 on SSD in my PC. Then I needed to use it on a laptop. I took out the SSD disk and put to the laptop instead of its HDD. Now Ubuntu doesn't boot, which means that after loading bios screen the laptop restarts. No unusual messages for me. The last one I quickly managed to see is "Entering multiboot bla bla bla"
I loaded Ubuntu from LiveCD and installed Boot Repair tools, then fixed GRUB, putting it on a partition with bios_grub flag.
- Order of disks to load from is OK. I have ony SSD and I choose to load from it
- I tried to switch AHCI/Compatible in bios (in case it helps, though I don't know exactly what it means), switch off Wifi and other devices in bios. This didn't help.
Do you have any ideas how to fix this? Any advices appreciated
