I get crash of Windows 7 pro x64 on my Z820,
crash appear with blue screen and I'm not able to restore from boot X image.
I decided to recover it with the recovery CDs from HP, unfortunatelly boot from disk doesn't start, I did few changes in Bios manager, with some info from cathed around web but nothing change, HP support suggested to update the bios (currently machine have 03.65) even BIOS update procedure doesn't start.
Have you some suggestion? I really frustrated about it.
thanks in advance.

STOP TRYING TO DO A BIOS UPDATE....................it's obvious you have little knowledge of system hardware or troubleshooting
you can damage your system beyond repair if something goes wrong or the update is done wrong/ whoever told to to do this is not a skilled tech and you should avoid any further advice from them
what recovery disk are you trying to boot from? is the optical drive seen in the z820 bios?
DO NOT DO THE STEPS LISTED BELOW YET......................we need some more information before we do a bios reset
again wait till we tell you to a bios reset
you do a Full Factory CMOS reset, by powering off the system remove the power cord then press the power button for 10 sec to drain the boards caps
now remove the side panel, locate the small cmos reset button and press it for 5 sec
(read the z820 service manual for where the cmos button is located)
now reassemble the system, power on a press "F10" to enter the bios, at the main page look to see if the DVD/CD drive is listed and if not let us know,.....now set the correct time/date and save/exit the bios settings and allow the system to boot

HP Support send me two DVD, System Recovery (windows 7 recovery Media for Windows 7 Products) and Operating system DVD Windows 7 Professional SP 1. I try to boot from DVD rom but recovery disk doesn't start. Could be the DVD/CD rom doesn't work at all, I have seen the green led blincking.

I build my own restore disks as the HP ones are now way out of date in driver/security updates so i've never used the HP set
the win 7 sp1 disk should be a normal OEM install disk that has the necessary SLP keys to self activate windows 7 on the z820 if your z80 originally came with win 7 (you should have a win 7 label/key on the top of your case) so boot from the win-7 disk install the os and then after win 7 is installed run the restore disk which should then create the recovery partition and install the recovery applications and z820 drivers/applications

I buy this WS with prei-installed OS but in German language, than I buy a Windows 7 in italian with a usb stick,
I had installed and it work till few days ago. Currently problem is that boot from dvd/cd doesn't start. I can try to install again windows from usb, but even there at that time I got prole with some setup in bios (AHCI-Raid AHCI...some like this) at end I had solved by change some of this parameter.

the bios should be at defaults, please reset it back to defaults
you should not be changing settings you do not fully understand as this will most likely cause more problems rather than solving them
the RAID+ AHCI setting is the correct (default) bios setting the other options are not used for 99.99% of users

Another parameter that I read around the web, it's PXE option rom(legacy or EFI) Mass storage option ROMS(legacy or EFI) and (Video option (legacy or EFI) this can lead the boot from DVD/CD rom
However it the face that I can 't run boot from DVD rom or from USB.

nor will you until you reset the bio settings back to the defaults, doing so will make sure the select boot device option is correctly enabled (F9 key)
and once the bios defaults are restored we can make sure the boot device load order in the bios is correct which should be
2. USB devices
3. Hard Drive
