I have installed Ubuntu on a Lenovo Thinkpad R500 2732, and I must update the BIOS.
On the Lenovo website, I am offered this:
BIOS Update Bootable CD for Windows 7 (32-bit, 64-bit), Vista (32-bit, 64-bit), XP - ThinkPad R500
I guess a bootable CD that would do a BIOS update is indeed what I need. (still wondering why it says "Windows" though... if it is bootable should not it be OS-agnostic?)
Not wanting to waste a CD, I copied the image to my USB stick:
sudo dd if=/home/nico/7yuj40uc.iso of=/dev/sdb1 bs=1M
And rebooted, after making sure USB is first in the boot sequence.
PROBLEM: It does not boot. Did I forget one step?
ls -lh 7yuj40uc.iso 25M file 7yuj40uc.iso /home/nico/7yuj40uc.iso: # ISO 9660 CD-ROM filesystem data '7YUJ40US ' (bootable)
(Scroll to the right: it says "bootable")
- UNetbootin does not work because it is not a Linux image.
- Some people on the Internet advise to copy the content of the ISO and do other steps. This ISO has zero ISO content so it would not work. If I mount the ISO, I can see it contains zero files.
