Boot Fail USB HDD

[montyw47]

Laptop Dell Inspiron 9200 1gb DDR 60gb internal drive, Intel 2200BG wireless card.
Booted from DVD drive UBUNTU LiveCD 7.10. It discovered and connected to wireless card no problem!!! Installed onto ANTEC enclosure 300gb Maxtor HDD. After removing DVD and trying to boot from USB drive, hard drive not found message and system stopped.

Formatted drive during install and set boot at 1st logical part.
BIOS boot Seq was set to:
USB First boot device
Internal hard drive next device

when running live the USB drive was SDB*
internal hard drive was SDA*
don't think GRUB set up boot sequencing right.
But booting from USB it should be SDA.

First partition is FAT32 2,000mb(2gb) and 2nd partition is EXTENDED for remaining space.
SDA5 first Logical partition 10,000mb EXT3
SDA6 2nd Logical partition(2,000mb)! SWAP

Any Ideas?

I think the first step is probably boot from the live CD with all you drives connected. In a terminal run

sudo fdisk -l

and post the output. We can then be clear about what partitions are actually on the disk and how they are being referenced.
Ed: Indicate which drive is internal etc in the post with fdisk output. Also indicate where you installed grub, where the /boot/grub/menu.lst file is and post its contents.
It would also be useful if you try unplugging the USB drive and reboot the system & see if you get your previous boot sequence/menu.

Hi and Welcome !

After removing DVD and trying to boot from USB drive, hard drive not found message and system stopped.

Thats strange. Its should either throw No Operating System Found or GRUB errors. Are you sure that USB disk connected properly?

Is your Lappy booting up fine from Internal HardDisk?

Formatted drive during install and set boot at 1st logical part.

I am not getting it. Did you set Boot Flag of first Logical Partition Or installed GRUB ( Boot Loader ) in its boot sector?
