DISC0 not detected

[PaxeSalute]

Hello everyone

Another Problem I have since the beginning of my Vista x64 Installation as second OS for my Dual Boot.

XP Pro works fine since the beginning and once in XP I can see either in Explorer and Device Manager and Administration Tools both of my HDD

Vista only detect one the one on which it is installed (second HDD DICS1)

I tried rescan in administration Tools no results.

All Boot File are on DISC0 (the one Vista does not recognize)

Any solution? I'd like to use EasyBCD but if Vista does not see the HDD with the Boot file on I almost sure I won''t be able to use EASYBCD under Vista.

Also When I restart my PC from Vista, BIOS does not detect anymore my DISC0, so I get a BOOT file not found and have to switch off completly and switch on again and BIOS is normal.
I think one problem is related to the other.

Thks in advance for your suggestions

It looks like my Long Time Load Vista is fixed.
I have a Keyboard & Mouse Wireless USB, yesterday I unplugged the USB and started Vista only with PS2 Keyboard. And the load time drop to 30 seconds instead of 10 minutes.
Once in Vista I plugged the USB, Vista detected it as new Hardware and install some Human device drivers and that's it.

Now Vista load in 30 Seconds, I heard it can do better but between this and 10 minutes I happy enough.

Beside this the other problem I had that if Restart from Vista , BIOS did not detect DISC0 with Dual Boot File, it's fixed too since the process with the USB plugged.

Also I think, my 3rd problem that DISC0 did not appear under Vista in Explorer, neither Device Manager, nor Administrative Tools, I could see it in explorer so all 3 problems were related together.

Thks anyway
