Grub Loading Stage1.5 Error 21

Registered: 2012-06-20 Posts: 27 Grub error Loading stage1.5, error 21 I get this grub error just after a fresh install of Arch. Dual booting Win7 & Arch./dev/sda1
Grub Error 21 Selected Disk Does Not Exist
100M Win7 *Boot*/dev/sda2 238G Win7/dev/sda3 200B /boot *Arch* *Boot*/dev/sda5 30G //dev/sda6 205G error 21 selected disk does not exist windows 7 /home/dev/sda7 6G SwapI know with other linux distro I've alway placed my boot flag on 100M Win7 partition. Guess since I have a /boot partition is a boot flag needed on both Windows & /boot? I've tried boot flag on just /boot partion and just 100M Win partition and I still get Grub loading, please wait Error 21 and blinking cursor. When I installed Arch I place grub on /sda. I've been browsing the web but figured I'd ask. Thanks.

Use either gparted or cfdisk.When I installed Arch I place grub on /sda.You need to install GRUB to /dev/sda, not "/sda". From the Arch install media run:# mkdir /mnt/arch # mount /dev/sda5 /mnt/arch # cd /mnt/arch # mount -t proc proc proc/ # mount -t sysfs sys sys/ # mount -o bind /dev dev/ # mount /dev/sda3 boot/ # chroot . # grub-install /dev/sdaThis will get you the "stage" files in /boot/grub. Alternatively, you can do this instead of the last line, since the alternate method from above is supposedly known to be less reliable (personally I have never had an issue with it, tho). If you still have problems, post your menu.lst.PS: I'm sure there's an easier way using only the GRUB shell, but I'm not that familiar with GRUB Legacy anymore. I use Syslinux now. Check the wiki.I am, however, 100% certain that the above method will work. "How to Succeed with Linux"I have made a personal commitment not to reply in

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

Join Date Feb 2009 Posts 42 [SOLVED] GRUB Error 21 Here's the problem: My laptop is running Fedora 12. 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 partiti

I just installed Ubuntu 5.10 on my computer. I have WinXP on my Master drive, and Linux on my Slave Drive ( both drives are on the same cable btw ) And on the first reboot I got a blank screen saying this: GRUB Loading stage1.5. GRUB loading, please wait... Error 21 Thats it. It then locks up. Right now, I'm using the live cd and I can't really do much. What should I do!? I did a google search but all I found out was that it seems to be a common problem and some people fixed it by changing some sorta config file (?) I dunno what it all means. I only got the CDs today. Please help.
