Hello, I hope you don't mind me jumping in. I'm having a similar issue. It first started a few nights ago, and after booting from the live cd and reading around, I saw it mentioned somewhere that it might help to update GRUB. I did this using sudo update-grub. This took care of the issue, with an unexpected, but not altogether unwanted result: instead of having to choose a temporary boot device to boot on to the external drive Ubuntu is on, I got a grub menu which showed the the OSs for both HDDS.
I thought all was fine, but a few days later, same thing. Updated grub again, and all was okay. Tonight, it happened again. When I try to update grub now it says:
I was hoping someone could help me resolve this issue once for and all. Here's the result of the boot info script.Code:ubuntu@ubuntu:~$ sudo update-grub /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?).
It looks like the problem is that there's no boot loader on the drive Ubuntu's installed on. Any ideas?Code:Boot Info Script 0.55 dated February 15th, 2010 ============================= Boot Info Summary: ============================== => Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in partition #1 for (,msdos1)/boot/grub. => No boot loader is installed in the MBR of /dev/sdb sda1: _________________________________________________________________________ File system: ntfs Boot sector type: Windows Vista/7 Boot sector info: No errors found in the Boot Parameter Block.

**UPDATE** So I removed grub-pc and reinstalled legacy grub. I then did sudo apt-get install grub-pc and it's at a screen asking me which devices I want to install grub to. I choose both sda and sdb and it comes up saying it failed to install to both. On the terminal I get
**UPDATE 2** Well, it looks like it's NOT grub legacy... but I rebooted the computer after this and was able to get the grub menu again. I just ran the boot info script again:Code:Setting up grub-pc (1.98+20100804-5ubuntu3) ... grub-probe: error: cannot find a device for / (is /dev mounted?). grub-probe: error: cannot find a device for /boot (is /dev mounted?). grub-probe: error: cannot find a device for /boot/grub (is /dev mounted?). grub-probe: error: cannot find a device for / (is /dev mounted?). grub-probe: error: cannot find a device for /boot (is /dev mounted?). grub-probe: error: cannot find a device for /boot/grub (is /dev mounted?). grub-probe: error: cannot find a device for / (is /dev mounted?). grub-probe: error: cannot find a device for /boot (is /dev mounted?). grub-probe: error: cannot find a device for /boot/grub (is /dev mounted?). /usr/sbin/grub-probe: error: cannot find a device for /boot/grub (is /dev mounted?). /usr/sbin/grub-probe: error: cannot find a device for /boot/grub (is /dev mounted?). grub-probe: error: cannot find a device for / (is /dev mounted?). grub-probe: error: cannot find a device for /boot (is /dev mounted?). grub-probe: error: cannot find a device for /boot/grub (is /dev mounted?). /usr/sbin/grub-probe: error: cannot find a device for /boot/grub (is /dev mounted?). /usr/sbin/grub-probe: error: cannot find a device for /boot/grub (is /dev mounted?).
