I was making an update on my Ubuntu 10.04 beta1 64-bit PC when, after reboot I get

PXE-E61: Mediaa test failure, check cable PXE-M0F: Exiting Intel Boot Agent.

No bootable device - insert boot disk and press any key

How did my boot record disappear ?

Tried all sorts of things - finally opened the chassis - for some odd reason the cable connecting to the hard-disk got burnt. The computer was on the whole night though, but that shouldnt be a reason. Shouldnt be a voltage issue as Im connected to a 1kVA Delta UPS which handles the voltage fluctuations (if any).

    well, that would have been the last option I was thinking about ;-) – Diskilla Aug 31 '10 at 22:06

Sounds like a grub (bootloader) problem. I'd suggest booting from a live CD, mount the file systems from the disk, chrooting into them and using grub to re-install the bootloader.

I am of course assuming that you know how to do the above, based upon the fact that you're knowingly running a beta release operating system.
