[SOLVED] - Grub Error 15 on Fresh Install

I've created a Boot CD from the archlinux-2011.08.19-core-i686.iso and booted from the CD.

I've used both Autoconfig and Manual to set up my 4 Gig USB Flash Drive - /dev/sdb


BOOT - /dev/sdb1: UUID="467fc66a-6c36-48ab-a7f3-69f449407927" TYPE="ext2"   Size=1003.53 Meg
SWAP - /dev/sdb2: UUID="f83191f6-cdf3-4647-80e2-86ac73063725" TYPE="swap"  Size=259.75 Meg
/dev/sdb3: UUID="fc7e8565-6668-4370-bb32-33d2d89ee28e" TYPE="ext2" Size=2.02 Gig
/dev/sdb4: UUID="00055f18-3e0a-48b8-a9c5-5593aacc2bee" TYPE="ext2"  Size=676.91 Meg
unallocated 1.68 Meg

Disk /dev/sdb: 4206 MB, 4206886912 bytes
130 heads, 62 sectors/track, 1019 cylinders
Units = cylinders of 8060 * 512 = 4126720 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00002773

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1   *           1         255     1027619   83  Linux
/dev/sdb2             256         321      265980   82  Linux swap / Solaris
/dev/sdb3             322         847     2119780   83  Linux
/dev/sdb4             848        1019      693160   83  Linux

No matter how I prepare the USB Flash Drive I get the Grub Error message as follows:

Booting Arch Linux

Root (HD1,0)

Filesystem type is ext2fs, Partition Type 0x83

Kernel /vmlinux-linux root-/dev/disk/by-uuid/xxx-xxxx-xxx-xxx ro

ERROR 15: File not Found

In Grub I've tried:
root (HD
and HD0, HD1 are the Options.  HD1 is my USB Flash Drive (sdb)
find /boot/grub/stage1    finds nothing.............
I'd think that stage1 would be found if Grub was installed properly.

I've tried EXT2, EXT3, and the following sizes....Boot as 100 Meg, Root as 1800 Meg, Swap as 256 Meg, and Home = Remainder (~1800).

I've searched this Forum and haven't found any answer that makes my USB Flash Drive Boot.  At this point I'm stuck.
Is there something I'm overlooking? 

Thanks.

Larry

Re: [SOLVED] - Grub Error 15 on Fresh Install

On BOOT (grub), your usb-drive is hd0, and hd1 is your installed hard disk. In other words, BIOS _always_ shows boot drive as first hard disk drive.

Re: [SOLVED] - Grub Error 15 on Fresh Install

I wouldn't keep swap on a USB stick, for the same reason that people don't keep their pagefile (Windows) on SSD's.

Re: [SOLVED] - Grub Error 15 on Fresh Install

djgera,
I've tried editing my Grub entry to make it hd0,0  but I still get errors that prevent me from booting.

Is it possible to get Arch Running on a USB Flash Drive?  If so, Is there any detailed documentation?
I've searched, but not found that information yet.

Thanks.

Larry

Try hd0 instead of HD0... Lowercase.

And by that I mean (hd0,0) – the USB stick as far as GRUB is concerned.

Re: [SOLVED] - Grub Error 15 on Fresh Install

Thanks, DSpyder I already had it as hd0,0.  I found the clue here to get my USB Booting.
https://wiki.archlinux.org/index.php/In … _a_USB_key

I used /dev/sdbx versus the UUID, and edited the /etc/mkinitcpio.conf, add the usb hook to the hooks array right after udev.
