gman14464
I'm trying to run UBCD to fix my computer. bios is set in the correct boot order (cd, usb, hdd) but skips straight to hd. hard drive is sata, cd drive is ide

relevant specs:
hdd: seagate barracuda 7200.7 80G
cd drive: toshiba ts-h552 dvd +/- r/rw

On boot, you should be able to press "Esc=boot menu" or another function key to manually choose boot device. You may have a non bootable or bad CD

Check your bios. Some have a setting to turn off ide in favour of using sata only.

Are you sure that the UBCD you created is a bootable image?

Depending on the image you have, the created CD may not be able to boot.

was the ISO actually burned as a disc image or a data disc?
data disc will just be the unexpanded ISO on standard CDFS
if the contents on the disc look like this:

UBCD521.ISO

then the ISO wasn't burned as an image but a data disc

quote from the UBCD site:
- After you have burnt the ISO image to CD, you should see the following structure on the CD if you have done it correctly:

c:\ubcd-extracted\
boot\
pmagic\
ubcd\
autorun.inf
license.txt

Does it have a prompt to hit any key to boot from cd? That is what we would get on the screen when booting UBCD.

Look for and disable any Quick boot / Fast boot / Quiet boot settings
called by different names in different Mfg. BIOS versions

also look for any setting that might indicate enabling the display of BIOS / Setup entry Key & boot options menu key

eg. displaying
Press F1, F2 ... to enter setup
and
Press F9, F10, F12 ... for boot options menu
options use different keys in different BIOS / System Mfg.

when the BIOS Quick / Quiet / Fast boot is disabled
and when display Setup, Boot menu etc. keys is enabled
you get more time to respond to any prompt for changing how the system is starting up

quick / quiet / fast boot is usually the offender as the goal of that BIOS option is to get to the OS as quickly as possible thus you usually have only a fraction of a second to respond before BIOS passes control to the OS boot loader on the HDD
same goes for the enabling of the display of setup entry key / boot menu key etc.

even with the boot order set to CD/DVD first, some system BIOS are just really sensitive or stupid, (especially with fast boot enabled)
so if it doesn't find the boot info on the CD fast enough or on the first spin / read attempt,
it just moves along to the next device in the boot order
