My PC won't start after installing the latest version of Ubuntu. I press the button to start the PC and then I see the BIOS start, but after that I get a black screen and nothing is happening. I can't even reinstall Windows 7 or choose between Windows 7 and Ubuntu.

Please help. I don't want to pay for fixing this. I don't remember the hardware, and since I can't access Windows 7, I can't tell you. The only thing that I know is that it is an HP Compaq 500bmt.

If you have a usb stick to hand you could turn it into a Ubuntu Live USB, boot into it and reinstall grub, this may help. Once in the live USB install "Boot Repair" and reinstall grub using this tutorial.

TUTORIAL

After this restart your PC and at least this should get you back into Windows if not Ubuntu as well. Hope this helps.

  • when i choose to boot from usb i get again the black screen :( wtf is happeing to my pc =/ ... any other solutions ? – sotos bic Apr 02 '12 at 10:27
  • What do you mean choose to boot from USB, do you mean once you have hit the Ubuntu options menu where you choose to install, boot into live and other options, or do you get the black screen as soon as you pass the bios? – Ross Fleming Apr 02 '12 at 10:50
  • i start my pc and then the brand of the pc (compaq) and down left it says esc for boot f10 for boot from lan etc . i press esc and resolution of screen changes and then it says to choose how i want to boot and i have some options . i press the one that is the usb and then nothing... – sotos bic Apr 02 '12 at 10:57
  • Are you 100% sure that the Ubuntu is correctly on the USB stick? Do have have another computer to test it with? – Ross Fleming Apr 02 '12 at 11:03
  • Also is there any way you could try booting from a Ubuntu CD rather then USB stick? As from your description it seems you do not have the option of specifically booting from USB. – Ross Fleming Apr 02 '12 at 11:07
  • i checked the usb on my laptop and it worked. i burned ubuntu-iso into a dvd and tried to install it in my pc again black screen . i checked it on laptop and worked . – sotos bic Apr 02 '12 at 11:29
  • Are you sure that your PC has a DVD drive and not a CD drive? Also would it be possible for you to enter the bios "setup" and see if you could change the boot order? I would suggest putting the CD/DVD drive at the top and then USB(Could be named " removable storage") next and then HDD and then Network boot. Now attempt to boot from USB and disk again. – Ross Fleming Apr 02 '12 at 11:33
  • it has a dvd drive . and i changed the priority but nothing happened again . i suppose that by having the pc on and the bios running it is not a hardware problem right? – sotos bic Apr 02 '12 at 11:39
  • It doesn't sound like a hardware problem to me. I know this may sound patronizing but have you tried inserting the USB into a different USB port, more specifically in a rear port rather than one at the front of the PC? – Ross Fleming Apr 02 '12 at 11:42
  • hmm no let me check from behind – sotos bic Apr 02 '12 at 11:43
  • oh my god ... i feel so stupid... well ubuntu from the back ports works – sotos bic Apr 02 '12 at 11:57
  • I'm so glad I could be of some help, now you can boot into Ubuntu I would suggest following the tutorial I linked in my answer so that you can boot into the operating systems you already have installed rather than reinstalling and loosing your data. – Ross Fleming Apr 02 '12 at 12:04
  • Out of interest, have you managed to recover your Ubuntu and Windows? – Ross Fleming Apr 02 '12 at 12:45
