I have a HP Paviion dv6t-1000 that lost the serial number, model and so on in the bios. Before I go on to what I did I am a bit confused on if I really have a dv6t. I purchased two HP Paviion dv6t-1000 at the same time from HP, both product stickers show them to be a model # Paviion dv6t-1000, BOTH P/N Kq574AV and both showed dv5t in the bios using bios f11. Not sure if HP sold me dv5's with dv6 tags. Anyways on both of them you have to refer to dv5 for the bios on HP site. Now on to what I did was used HP DMI TOOLKIT to enter the serial number back on the one that lost all the info and was able to boot to the vista that came with the system. I decide upgrade to win 7 and on the first reboot all I can get now is the hp splash screen, can't enter bios or boot to another device now. I search here and found the BIOS recovery, "Window Key + B" method but I must not have the files right on the usb. Anyone that could help me figure out what I am doing wrong will be appreciated.
