Re: [ilugd] Grub Error 21
Actually, grub stage1 is in your MBR. for removing grub from MBR, use if=/dev/zero instead of /dev/null. i think, you should try what Kazim is suggesting.

Then using a Live CD, install GRUB on your USB HDD too, separately. Now you've a GRUB on your local disk as well as a complete one on your external disk. Using boot priority, you can boot either. Here are instructions on how to install GRUB. I prefer installing it using GRUB prompt. http://www.bo.infn.it/alice/alice-doc/mll-doc/linux/advanced/node49.html - Kazim Zaidi ___ ilugd mailinglist -- ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd Next Event: http://freed.in - September 28-29, 2007 Archives at: http://news.gmane.org/gmane.user-groups.linux.delhi http://www.mail-archive.com/ilugd@lists.linux-delhi.org/

What I intend to do is install GRUB on my external HDD and remove it from the internal HDD. So my stage1 and stage2 would be in the USB HDD. And i will select that as my boot device when i need to boot into Ubuntu. I suppose that should solve the problem right?? I will be removing the GRUB from MBR on my primary disk using $>dd if=/dev/null of=/dev/sda bs=446 count=1 But i suppose there are problems with this. This wont restore my Windows boot loader right??

Re: [ilugd] Grub Error 21
your stage1 of the GRUB is installed in MBR, while stage2 is in external USB HDD. so, without the external USB HDD plugged in GRUB won't be able to get into its stage2 (which does the majority of GRUB's magic). **installing GRUB on the external disk would still give you no solutions !!

[ilugd] Grub Error 21
Hi, After successfully installing Ubuntu 7.04 on my external USB HDD, I am facing a problem. GRUB is installed on my primary hard disk. SO when i boot without having plugged in the USB Hard disk, i get the following error. GRUB Loading please wait.. Error 21 After looking up what error 21 means i found out it means that a disk could not be found. Is there a way to circumvent this problem? Should i install GRUB on the secondary disk, and remove GRUb from this disk? That seems like the better solution but I dont really know how to go about just installing GRUB on my USB HDD and keeping my existing Ubuntu Installation. -- Puneet ___ ilugd mailinglist -- ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd Next Event: http://freed.in - September 28-29, 2007 Archives at: http://news.gmane.org/gmane.user-groups.linux.delhi http://www.mail-archive.com/ilugd@lists.linux-delhi.org/
