    Wiped critical info from bios HELP!!

    O.k here's what happened...
    Knowing that Microsoft will no longer be supporting windows 7 next year I wanted to duel boot my laptop running win10 & Linux mint.
    I installed win10 but wasn't happy with the install so went ahead for a reinstall, somewhere along the way I accidentally wiped a partion which must have held BIOS info like s/n, p/n, uuid, etc.
    Now when I boot it tells me it's in a non commited state, I tried to rebuild the partition via cmd & no luck, I realise that it needs rebranding & I have HP DMI software But to make matters worse there is no physical info on the laptop such as serial no, model no etc.
    I'm at a dead end and dont want to make matters worse by attempting things that are going to dig my hole deeper so have turned to the forums, I consider myself a basic user this is my first ever post and Im out of my depth.

    The install was a UEFI Win10 on GPT formatted partition from usb.
    My laptop is an old but stable HP Elitebook 8540p.
    i5
    2.53GHz
    8 GB ram
    BIOS Revision 68CVD Ver. F.60
    Thanks in advance for any help.

      The BIOS shouldn't be on the hard drive! We're not talking about 1980s or some 1990s systems, where you can't get into the BIOS without a drive, by hitting a key.

      Reminds me of an old system I had on two different occasions, where to access the BIOS, you had to have a floppy disk, (or a hard drive) because that's where the setup utility was, if not also written to certain hard disk drive sectors.

      Even on newfangled BIOS systems, (a.k.a. UEFI) you are usually only going to end up in shit creek, when you can't disable "Secure Boot".

          Sounds like you nuked the bootloader.

                  UEFI stores some shit on a hidden partition, but it's not critical - wipe the drive clean and go into the bios and check it's settings.

                      "there is no physical info on the laptop such as serial no, model no etc."

                      It should be on a sticker on the base or inside the battery compartment.

                          ASUS Zenbook Pro Duo UX8402ZA BIOS
                          by pirati
                          Hello everyone,

                          I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.

                          When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.

                          I decided to try flashing a new BIOS, but since I didn’t want to desolder...

                          ASUS TP500LA BIOS request/repair/merge?
                          by jbonavita
                          Hi, my laptop wont boot at all
                          With original bios no POST, only LED lights
                          With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
                          Some issues
                          A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
                          B- If updated from 500LN version 203 to 300, the battery stops being recognized

                          Things I tried

                          1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...

                          [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
                          by zenius
                          Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

                          Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

                          HP Pavilion Gaming Laptop 15-ec2523nd - Dimm2 slot disabled after corrupt bios repair? Advice requested.
                          by Bloodhoundje
                          Hi everyone,

                          I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.

                          I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.

                          After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.

                          I have desoldered the bios chip (GigaDevice...
