Problem with Flashing Boot Block: What to Do?

HP laptops are known to have flashing boot blocks, according to many users. This problem may appear after installing HP software or Windows upgrades. This problem may also arise if you have updated your BIOS. A black screen will appear with the message “Flashing Boot Block – percent” if this problem is present. When the flashing is finished, the blue box will indicate “Flashing Boot Block – Flash Complete!” when the flashing is finished. However, you will be unable to boot into Windows in any scenario.

The boot block is a term you may have heard of.

The boot block is a small section of memory in the BIOS that stores the bare minimum of booting instructions. This information cannot remove through a standard BIOS upgrade. A Floppy drive and an ISA video card are the only devices that Boot Block can boot from. Boot Block lets you use the floppy disc to recover the BIOS if the BIOS update fails.

If the boot block code is not altered, the shorting trick should work. The shorting method should not work if the /sb change is used rather than just the /wb switch while flashing the bios. For each chip, the two parameters that must crimp to generate a checksum error are unique. However, the address pins with the highest numbers are frequently used (A10 and above).
