I installed BackTrack 4 onto an external USB hard drive using a LiveCD. Now when I boot my laptop (external HDD removed), I get this: Code: GRUB Loading stage1.5. GRUB loading, please wait... Error 21 I don't get this. I never touched anything with my internal drive. Well, maybe. When I was reviewing what partitions the installer was going to format, the swap partition for my internal drive (Fedora) was set to be formatted even though I did not specify this. I figured that wouldn't cause any problems. Also, Fedora never used to show GRUB loading at all. Screen was blank until Fedora starting loading. Maybe this means that this is a copy of GRUB from my BackTrack disc? Also, I ran 'fdisk' to look for anything suspicious and under /dev/sda1 (internal drive, boot partition) it says "Partition 1 does not end on cylinder boundary." Please, please help. I have a half-completed research paper on this drive and LOTS of homework and about 70 O'Rielly books. 03-27-2010 #2 devils casper View Profile View Forum Posts Private Message View Articles Super Moderator Join Date Jun 2006 Location Chandigarh, India Posts 24,776 Installer of Backtrack has installed its GRUB

Re: Got "Error 21" message when in GRUB « Reply #1 on: September 04, 2012, 02:32:13 PM » Quote21 : Selected disk does not exist This error is returned if the device part of grub error 21 a device- or full file name refers to a disk or BIOS device that is not present or not recognized by the BIOS in the system.From info:/grub/Stage2 errors ..... you can use Konqueror to see all the error messages by entering that in the location bar.I would suggest checking the cables .... power and data going to the disk ..... pull them and reseat them with the power unplugged.Then try to boot again.
