I hope your laptop still can boot up from the DVD drive, so you can make a bootable DVD media with the BIOS flash (using other computer) to replace the current corrupted BIOS.

My toshbia c655-S5125 lost power in the middle of a disc repair and now windows will not boot. i can get to the bios, but can not get windows to boot from the hard drive or the cd


Sounds like a corrupted operating system. You need to reinstall windows from scratch. Also the hard drive may be corrupted and you may need a new hard drive. Since you can't really do much of anything you will need a copy of the windows OS on disks If the bios will not let you boot from a CD install disk then I suggest you need a professional to help you. You need to have a BOOT DISK in the cd drive for the system to get further than the bios software. If that won't work then your problems are deeper than a corrupted hard drive.

HP Pavilion m7330n: Possible corrupt bios, solutions anyone?


what OS? is this XP? with SP3 or not? needs it. if XP.
you never need to delete old hdd, drivers ever.
reg booster?
would not reboot. the HDD fails>?
its not really BIOS, corruption at all,
if the CMOS battery is above 2.9v then no corruptions happen.!
the ROM part will not corrupt but the ram part can , easy, Battery.
check this battery any time bios forgets things this battery is the
no forget feature (CMOS NVRAM battery backup)
Bios can boot to any dvd, or cd, if you plug it and and select it.
BIos can boot the HDD, or SSD, or USB stick. and more, F9 key?
never use reg booster, avoid it like the plague,
any reg modifying programs are nothing but trouble. !!!

m7330n circa 2005. a desk top (or media center) Athlon 64 X2
so what DVD are you installing,
Sata, or PATA
tell what you have and why you need and adaptor,(btw i have them all here, from you name it ,to what eva.)

the HDD is SATA.
but what is the DVD jacked into?
dvd drives come in;
PATA
SATA
USB
what is yours?

Computer is booting from a non-bootable source

Many times this error is caused when the computer is attempting to boot from a non-bootable CD-ROM. First verify that no CD is in the computer, unless you are attempting to boot from a CD.

I try update my bio on my ao0751h netbook acer, and doesn't successfully, now my netbook doesn't turn on. How i recovery a bios?


Solution 1: Boot-block BIOS
Modern motherboards have a boot-block BIOS. This is small area of the BIOS that doesn't get overwritten when you flash a BIOS. The boot-block BIOS only has support for the floppy drive.If you have a PCI video card,you won't see anything on the screen because the boot-block BIOs only supports an ISA videocard.
Award: The boot-block BIOS will execute an AUTOEXEC.BAT file on a bootable diskette. Copy an Award flasher & the correct BIOS *.bin file on the floppy and execute it automaticly by putting awdflash *.bin in the AUTOEXEC.BAT file.
AMI: The AMI boot-block BIOS will look for a AMIBOOT.ROM file on a diskette. Copy and rename the correct BIOS file on the floppy and power up the PC. The floppy doesn't need to be bootable. You will see the PC read the floppy, after about 4 minutes you will hear 4 beeps, this means the transfer is done. Reboot the PC and modify the CMOS for your configuration.
Solution 2: Get a new BIOS chip
  1. Contact your motherboard manufacturer to see if they sell BIOS chips. Some motherboard manufactures send them for free.
  2. Contact a company that sells pre-flashed chips, like Unicore Software, FlashBIOS.ORG, BadFlash or Bios World
Solution 3: Hot-swapping
Note: I'm not responsible for any damage this method may do to you or your computer !
  1. Replace the corrupt chip by a working one. The best option is to take the working BIOS chip from a motherboard which has the same chipset although that's not absolutely necessary. It just has to give you a chance of booting into DOS. Before pulling the working BIOS chip out of it's original motherboard, set the System BIOS cacheable option in the BIOS to enabled.
  2. After you have put the working BIOS in the motherboard with the corrupt BIOS boot the system to DOS (with a floppy or HD).
  3. Now replace (while the computer is powered on) the working BIOS chip with the corrupt one.
  4. Flash an appropriate BIOS to the corrupt BIOS and reboot.

Solution 4: (for Intel motherboards)
  1. Change Flash Recovery jumper to the recovery mode position (not all products have this feature)
  2. Install the bootable upgrade diskette into drive A:
  3. Reboot the system
  4. Because of the small amount of code available in the non-erasable boot block area, no video is available to direct the procedure. The procedure can be monitored by listening to the speaker and looking at the floppy drive LED. When the system beeps and the floppy drive LED is lit, the system is copying the recovery code into the FLASH device. As soon as the drive LED goes off, the recovery is complete.
  5. Turn the system off
  6. Change the Flash Recovery jumper back to the default position
  7. Leave the upgrade floppy in drive A: and turn the system on
  8. Continue with the original upgrade

"bootlock" When I turn the computer I get a message


The Boot Block

The preceding section discusses updating the program code in the system BIOS by flashing it (replacing it under software control). If the flash procedure is done improperly, the BIOS code can become corrupted, which will cause the system to go into an unbootable state. Many newer systems come with a feature where a 4 KB "boot block" program is included as part of the BIOS. This is a tiny piece of code whose job it is to recover from a situation where the BIOS code is incorrect or corrupted.

If your motherboard supports this feature, when the PC tries to boot and finds the BIOS code corrupted, the boot block will try to recover the BIOS code, usually by reading it from a specially-prepared floppy disk. You may have to change a jumper on the motherboard to enable this capability, and you may need to make use of a "plain vanilla" ISA video card. The boot block will load the BIOS code and then when you next reboot, the regular BIOS code should be in place and the problem resolved.

You will need to follow the special recovery procedure outlined by your motherboard manufacturer if you want to take advantage of this feature.

Corrupt & Locked Bios


When you flash the bios (normally from a floppy drive) it should overwrite anything that is there.
In this case you must boot from the floppy. Unfortunately, with a laptop you don't have that option.
I suggest you put the bios flashing utility that you probably downloaded with your bios update file on a flash drive. I think your laptop has the ability to boot from that.
Anyway, on startup, press F12 until you get the boot options and try that.
I take it that you know the support site URL, but just in case, it's support.dell.com

Computer will not boot after bios update


you updated the bios?

Its possible that your bios update failed and the bios is now corrupt.

try to rest the bios by th bios jumper, consult your manual or just remove the power and the battery for a hour and try again.

If the bios is corrupt it would need to be removed from the motherboard and reprogrammed.
