HP Pavilion laptop will only boot w/o harddisk, MBR damaged

When booting up, my HP Pavilion DV5-1199ez laptop (running Vista Home Premium) shows the HP logo in the middle and a message saying I can press esc to access startup options. If I hit esc, nothing happens. Hitting F11, same story. The system will not boot from the DVD drive either. The only way to get the laptop to boot is to remove the harddrive. I'm pretty sure the MBR is damaged. I can't try to fix the MBR from the Vista DVD setup menu as the system won't start with the HD in. Any way to get round this?

My hp laptop with windows vista home premium is not booting and showing to insert bootable disk, which I don't have.how i can get this


The installed Windows in your laptop has been corrupted beyond repair - you will have to reinstall it.
For that pres F11 during boot to launch the HP Recovery Manager from the recovery partition then follow the instruction. If even that fails it means that the hard disk itself has failed - the disk will have to be replaced and to reinstall Windows you will have to order a recovery cd for your exact model from HP.

Invalid disk system will not leave screen


that error happens when you have a nonbooteable unit inserted or when your OS master boot record gets damage and the bios doesn't find the OS boot up loader.

check in the bios the boot order settings

usually is like this

1 - Floppy
2 - Cdrom
3 - HardDisk
4 - Network

there can be more options but those 4 are what we care now. change the order in what the system checks for a boot media

like this

1 - Cdrom
2 - Harddisk
=============== place any other device in any other after # 2

If you still get the message then make sure that you laptop has a OS installed ( if it has one already) then try to repair the MBR (master boot record) using the os install cd and the recovery console ( applies to Windows XP, Vista, 7 ).

Otherwise Install a operative system in the laptop and that should take care of the message.

We got the problem in our internal segate harddisk. when the system is on, shows the error message of Boot disk failure.


This sounds like a problem with the hard drive's MBR (Master Boot Record) If you have a windows xp disk, insert it and boot from it, make sure that your cd-rom device is set as the first in the list on your boot priority in your bios. Here are the steps for xp and vista

So how can you repair your damaged MBR? Here are the steps to follow:
1. First, restart your computer with the Windows XP setup disk in the CD drive. If you don’t have your original disk, borrow one or download a ISO image from a torrent site.
2. When prompted, boot from the CD drive by pressing any key. If Windows loads automatically, you will first have to enter the BIOS setup and change the order of the boot devices to start with the CD drive.

3. Once the setup loads, you will see the option to press R to repair a Windows installation.

4. Once the Recovery Console loads up, you will have to type in a number that corresponds to your Windows installation. This is normally just 1. Press Enter and then type in the Administrator password.

5. Now at the prompt, type in fixmbr. Your damaged MBR will now be replaced with a new master boot record and your computer should now be able to boot properly. Note that you may also want to run the fixboot command to repair the boot sector with a new one.
Also, make sure you only use these commands on a system with one operating system installed. If you have more than one operating system installed, fixmbr and fixboot could mess up everything.
Fix MBR in Vista In Vista, the procedure to fix the master boot record is a bit different. You have to start up Vista in the Recovery Environment and then run the bootrec command. Here’s how.
1. First, load up the Windows Vista disc in your drive and press any key to boot from the disc.
2. Choose the language, time, currency, etc and click Next. Now click on Repair Your Computer.

3. Choose the operating system to repair and click Next. When the System Recovery Options dialog comes up, choose the Command Prompt.

4. Now type bootrec.exe and press Enter. This will rebuild the boot configuration data and hopefully fix your problem. You can also run the command with switches to fix just the master boot record (/fixmbr), the boot sector (/fixboot), or rebuild the entire BCD (/rebuildbcd).
If you are still having trouble with loading Windows, post a comment and I’ll see if I can help! Enjoy

File header checksum does not match computed one. ???


You have one or more critical corrupted file/s which prevents the laptop from booting up.
To get the laptop operating again, you need to insert the Windows Vista CD and do a Repair and if this fails you need to install Vista again.

yes you'll have to format the drive before you put xp on...you can use a boot disk with something like fdisk on it...you can boot using a HIREN boot disk (which has FDISK on it) or Roadstarter which is a bootable CD with a whole host of utilities including FDISK.....
or boot with a windows XP disk and choose the repair with console option ...at the command prompt type in FDISK and you will wipe all the data and partition tables ....giving you a raw data drive to install Win XP to

I/O error. HP 1720n won't boot


Run diagnostics on the hard drive (Normally provided either in the F8 or F12 boot menus) and se if you get a failure.

If the drive passes diagnostics, boot to the Vista DVD and run the repair option. (Note: you may have to the Vista repair process 4 or 5 times if there are multiple errors to be resolved)
