Hi

I am try to install OEL 4 on a external USB hard drive, but till now have not been able to successfully boot from it. Every time it boots, it displays "GRUB" on top left corner of the screen and does nothing more.

My system:
Dell Inspiron 6400 - Core 2 Duo
2 GB Ram
Internal HDD - 80 GB SATA - with Vista
External HDD - 250 GB SATA (seagate) - connected through USB. - target drive for OEL 4.

The OEL 4 Install:

I installed the Linux in 'expert' mode on the External HDD successfully with no error messages.

Disk config:

/boot - sdb1 - ext3 - 102 MB
/ - sdb2 - ext3 - 195000 MB
swap - sdb3- swap - 1984 MB
sdb4 - Extended
/xp - sdb5 - vfat

After installation i into linux rescue and create new initrd files with USB storage; here's how.

mount /dev/sda3 /mnt/sysimage
mount /dev/sda1 /mnt/sysimage/boot
chroot /mnt/sysimage

mkinitrd --preload=ehci-hcd --preload=usb-storage --preload=scsi_mod --preload=sd_mod /boot/usbinitrd`uname -r'.img `uanme -r'

and edited the GRUB.conf file to point to new initrd file and changed root=LABEL=/ to root=/dev/sdb2

so that's the long and short of it. Any help would be most welcome.
