[SOLVED] Booting problem Grub loading stage 1.5 error 21 Windows 7 openSUSE external hard driv
location: linuxquestions.com - date: July 28, 2011
A few days ago I installed openSUSE 11.4 on a 1TB HP external hard drive. I have some very important files for school and personal work on my main hard drive, running windows 7, so I made sure the installation only affected my external hard drive. With the external hard drive plugged in it boots just fine but when it is un-plugged it says Grub loading stage 1.5. Error 21 and it won't do anything. This kind of pisses me off because there were no warnings and nothing was supposed to happen to my main hard drive. But this has already happened and now I want to know if there is any way I could fix it so I can boot windows 7 normally and still boot openSUSE with the external hard drive plugged in. Thanks in advance to anybody who can help.

Recently installed Linux to an external HD. Now whenever I want to run Windows, if the external is not plugged in get the above error. If it is plugged in, the BIOS comes up and I need to select which platform to run. I believe it is a partitioning issue which I did not do when installing. The laptop does not seem to recognize the HD. Please help.

I have had ubuntu on my PC for 2 years without any problem. I am dual-booting between Ubuntu and Vista from a 2yr-old TOSHIBA laptop. The version of Ubuntu I was using is 9.10 (ok, should have updated a while back, mea culpa...)
Yesterday I couldn't load Ubuntu and I got a message
ALERT! /dev/disk/by-uuid/[long number] done not exist. Dropping to a shell!
I managed to sort out the problem thanks to this post
and used Ubuntu without any problem.
Now today I tried to switch the computer on again and I am getting the error message
GRUB loading stage 1.5
GRUB loading, please wait...
Following the advice on the post above, I updated GRUB to GRUB2 last night. Maybe I shouldn't have...
The screen with the GRUB error message comes before the screen that would let me choose between Vista and Ubuntu and won't let me use a command prompt or anything. The only thing I seem to be able to acce

I've used gutsy before and it kind of did the same thing. I had to edit menu.lst to get it to boot both os's right. Now I am trying to get back into ubuntu on a 64 bit rig. I have windows 7 on a 500g sata drive and installed ubuntu on a 40g ide drive. I have the 40g drive 1st in boot order.
I've tried the map command but it didn't work. Hear is the system info. Any help would be great.

GRUB loading stage 1.5.: Error 22

I have a computer (asus - pc - windows 7) my dad installed linux onto it. Now i want to give the computer to my mom (cause i have a new one). Before doing so, i wanted to reboot the computer to factory settings. But since that was not so easy with linux on it, I tried removing it by putting in the backup DVD's from windows 7 into the computer. It succesfully did what it was supposed to do. But now i try to start the computer, and i get this message on a black screen:
GRUB loading stage 1.5.
GRUB loading, please wait...
I looked around for the meaning of this error, and apparently i somehow deleted my booting system, so now my computer can't reboot.
My question now,... is this correct? and more importantly, how can i fix it! i looked around but can't find anything relevant.
This PC is still really good and I hope that you guys can help me with this, cause I sincerely don't know what I have to do!
How to avoid GRUB error 21 when I remove external hard drive
location: linuxquestions.com - date: December 29, 2006
Hi, I have a laptop with Windows XP on the internal hard drive and Fedora Core 6 on an external hard drive. I use the Grub boot loader. It works great as long as the external hard drive is attached.
However, if the external hard drive is not connected then Grub gives Error 21. I understand that this is because Grub was expecting both hard drives to be available. I am looking for a way to allow booting Windows XP, when the external hard drive is not attached.
I tried this:
I booted off my Fedora Core 6 CD and did linux rescue.
I edited grub.conf by commenting out all the lines for booting fedora and all lines referring to (hd1,0) the external hard drive. I then edited device.map to comment out the line for (hd1).
Unfortunately, I would still get Error 21 if the external drive is not attached.
I appreciate any help. Thanks!
