I can't install Ubuntu-14.04-desktop-amd64 on my Lenovo Thinkpad W510, using USB. I want a dual boot with Win7 and the latter is already installed.

Installing Ubuntu 9.04 from an old Live CD was possible without any problem, but after creating a bootable USB stick with Universal USB Installer according to Ubuntu instructions, I simply can't get past the menu and I can't do anything from there.

Whether I press Try without installing, Install or Check disc... I get to a black screen with some text on it. I waited for more than 10 minutes to no avail.

Using F6, I enabled nomodeset, but that did not solve anything. I also checked the ISO md5sum before burning and it was [ok].

Any ideas, please and thank you very much!

//later edit: fixed by using another USB stick.

It failed to mount the root filesystem from the USB stick. Things to try:

  • Check the md5sum on your downloaded image is correct
  • Try your USB stick on a different PC
  • Try a different USB stick
  • Install from a CD

I had a similar problem. Trying a different USB did the trick – Deecaf May 5 '14 at 19:45
Thank you for your replies. I checked the md5sum of the ISO file after downloading and it was correct. I will try using a CD instead, although with this stick I managed to successfully install Windows... – watt May 6 '14 at 7:26
Seems like it worked fine when using another USB. Although my stick was fine since I installed Windows from it. Thanks! – watt May 6 '14 at 21:17
