I have been attempting to install Cinnamon (mint 13) onto an Acer Laptop using an external Seagate 250GB USB 2.0 Hard Disk. The installer runs fine, however when booting, after selecting the installed image from GRUB, I get an error message stating that it can't find "HD0". I checked on the forums, google searches, youtube, etc, trying to find how to properly configure the boot process (I'm assuming GRUB) to look at the SDA devices instead of the non-existent internal hard disk (disk fried a day or two ago). At this point, there is a fresh install of Mint 13 on the drive. Any assistance would be greatly appreciated.
