I'll spare you the rant on dealing with "cracks" but will say that damaged or corrupted firmware in BIOS's is a major problem that is not always correctable. It is possible you have bricked your system. Especially if the BIOS is not in a socket but hardwired to the mainboard and can't be easily replaced.

The problem is that if the BIOS is the issue you aren't going to get past POST to read anything from any disk [hard, USB, CD-Rom] so the system becomes totally unbootable from any source because the system is unaware of any of these sources as the BIOS firmware hasn't provided the system the data to access them. None of the I/O's will function so you won't be able to flash the BIOS ROM with an replacement for the damaged code.

Your best bet is if your BIOS is socket monted, in which case you can purchase a replacement and swap it out for the damaged one which will resolve your problem as the code on the new one will be intact.

You can do it even if its not socketed, but un-soldering and re-soldering a BOIS chip onto a mainboard without damaging the tracings is no easy trick even for an accomplished repair tech.

Sorry I couldn't do better for you. I hope it works out.

Hi,

Your not going to be able to update the BIOS without having XP installed on the computer.
I had the same problem myself as a motherboard i had would not update with Win 7 installed.
If you have a spare hard drive and an XP install disk then i recommend installing XP on that and then download the exe BIOS update file and run it from within Windows to update the BIOS.
After that just turn the PC off, put back your Win 7 hard drive and your good to go.


Regards.

I have hp dv4-1465dx, how to reset bios without having OS


Hello,

Was Windows 7 the operating system that came with

your System? If not, What I would advise you to do

is this:

Check HP website to find out if your Laptop supports

Windows 7.

If it doesn't, then I would advise you to

PLEASE change it back to the operating system

that came with your system, or better still, the

operating system that it supports.

The reason is because that is exactly what I faced

two weeks ago....

I changed the operating system for my PC to

Windows 7 ( Even though it doesn't support it)...it

worked fine for a while, then later it started to develop

faults after a while...like stuttering, mouse pointer

moving round the screen, graphics displaying

improperly...etc.

I first thought it wasn't a big deal, so I fixed it by

repairing the drivers, and it worked fine once again...

After using that same crack that you said you used,

I started getting "Multiple Hardware Error"!

It would just Power on, Show HP Logo, Show

Wireless LAN indicator Led ON, and It will freeze

there. I could not even enter the BIOS.

In short ....Now as I'm typing, the system is

with HP Service Centre for they have to change the

Mainboard Outrightly!

So PLEASE, if your system was not specified

Windows 7, use the Operating Systems that it

supports.

Then go to HP Website and download the original

BIOS settngs for your Laptop then repair your

system with it.

But if it is the one that came with it, then let me know

so as to tell you some quick fixes.

Hope this helps you out.

Goodluck and thanks for using fixya!

To make sure you install back again your Windows Vista and Windows XP is this.
First:
  1. Go to Bios Setup and change the setting of your Hard Disk drive from Sata to IDE mode.
  2. Boot priority the CD/DVD Rom to run your Bootable CD/DVD.
This setting are quietly working, good luck!
