hi, I'm just trying to install windows XP on to run from my new portable HDD. I have a hewllett packard PC and i press F8 and go into the startup bios and there is no option to boot fromm portable HDD, only from CD or Floppy DD or inbuilt HDD or PCI. I select boot from my XP CD but when i try to install on my new portable HDD it says my computer cant see it to install. i can create a partition on it and format it but cant install XP onto it. Is this because the computer cant boot from portable HDD on startup that boot CD wont let me install onto it ? if so how can i get around this, i was thinking i either need to upgrade the startup bios or select boot from Floppy DD or CD with a program that allows startup access to Portable (USB) HDD. I have an old version of "Norton Ghost" on floppy and have tried to coppy HDD to HDD but it doesnt seem to see the portable HDD either only the inbuilt 1. I can install XP onto my USB HDD thru another computer I think but only options to boot from startup will still be CD, Floppy DD or inbuilt HDD. Thankyou for reading this and any efforts to help would be greatly appreciated. Merry christmas and HAPPY NEW YEAR ALL!
