I'm trying to give my old laptop a new life. The screen broke, so i removed it and i am planning to turn it into a media center. It's a HP Pavilion M6 laptop.

It perfectly starts from a live CD, but when I install Ubuntu/Lubuntu/Xubuntu i get a black screen and after a few minutes a screen full with weird characters. i tried adding radeon.modeset=0 and video=LVDS-1:d to my GRUB command line but this didn't change anything at all.

When I go in recovery mode, I get error gave up waiting for root device. Then I found online that it should be possible to reach the hard drive, but in /dev the entire sda is missing while working from the (initramfs) prompt, while on the live CD I see it.

How can I fix this problem? sudo parted -l shows this:


update 1: now i get this error : ALERT! /dev/disk/by-uuid/xxxxxxxx-xxxx-xxxx-xx$ does not exist when i change in the grub setings it should use /dev/sda1 instead it gives the same error. from the live cd i can still see this harddrive

update 2: The entire /dev/disk doesnt seem to be there in the initramfs console. it also seems to be stuck on "Switched to clocksource tsc" for a long time. I also tried formatting to ext3 and setting a rootdelay=90 but both didnt help

  • Do you get the "weird characters" screen during installation or after installation? Could you share the output of sudo parted -l from a live CD? – Andrea Lazzarotto Jun 26 '16 at 20:56
  • it doesnt show any signs of problems while installing.. it happens after the reboot of the installation. this is what sudo parted-l outputed: image-share.com/ijpg-3268-276.html – Mark Smit Jun 26 '16 at 21:37
  • Have you tried adding the nomodeset kernel option at boot (in GRUB)? I'm not sure if it'll help, but it's worth a try – Nick Weinberg Jun 26 '16 at 23:12
  • I tried to do this.. it gets me partly to the answer.. now i get the same error as i did in recovery mode. – Mark Smit Jun 27 '16 at 16:24
