Cann't boot to offical Windows 7 install disc in BIOS?

I tried to clean install Windows 7 Professional 32-bits to replace my existing XP Prof in BIOS Environments, which is currently using an Asrock's Conroe1333-DVI/H R2.0 OLD motherboard without success! I could configure the MB to boot from my DVD Drive but, despite it can boot into either Linux Boot Discs or even the original XP Pro install discs, it just cannot boot my Windows 7 Professional FULL install disc at all. My DVD Drive just flashed a few times and my PC then came into a total freeze, i.e. no HD activities nor any signs of my Windows 7 FULL install disc activities IF I inserted my Windows 7 Pro FULL install disc into the DVD Drive and rebooted.
However there is nothing wrong with my Windows 7 FULL install disc because I had tried it on another PCs, two of them alternatively, and it booted alight in each case. So there is something "unique" in my Asrock PC which just refused booting into this Windows 7 disc. This Windows 7 FULL disc is genuine and has its only Product Key, which remains un-used at the moment. Any one may have some suggestions???
To be honest I'm suspecting the Asrock's MB Firmware may take a part in that but UNTIL it is proven most likely, I don't want to flash my MB's FW as it could be damaging IF I did it wrongly!!!

if its a modern rig try making sure you are not using uefi boot.

Just looked the Asrock site, latest firmware is v2.10. What's the current version on the m/b?

Since the symptoms point to a compatibility issue, you should upgrade the BIOS to the current version. Unless you're very unlucky and get a power cut when writing, the upgrade should be straight forward.

What is "uefi boot" may I asked??
Thanks for the reply!

UEFI Boot

Thank you for the reply! I did look into Asrock's web-site as well. My current MB's FW is P2.0 which has never been flashed since the day I bought it couple of years back. Their latest corresponding MB FW is R2.10, which I believe is NEWER than my existing one already on my MB.
It seems like the only way to find out is to flash my MB FW to this latest R2.10 as suggest by yourself, and been thinking about it myself!!
Just to find a suitable time as my wife is using it constantly to view her internet stuff...

It sounds like you have a problem with the DVD drive. Try another DVD drive if you can.

Thank you for the info.. I should have consult the "Google"!!!

The DVD Drive is brand-new and has been booting O.K in various Linux, and even Windows XP install DVD, bootable DVDs from the same PC. So it is most likely SW/FW related for my problem.
Thanks

This probably not related but on another forum a poster had a similar issue and fixed with the following:

I figured out my problem,
I connected my monitor using HDMI, which was not good for windows 7 installation.
I went and bought a DVI to VGA adapter and cable and it installed fine.

Are you using HDMI by any chance?
