HP Compaq 510 - no boot

February 14, 2012 at 19:01:20
Specs: Windows XP
My laptop is not booting up. When you turn it on, it goes to the Windows loading screen and a blue flashing screen appears after then it goes back to the loading screen. This continuously happens when the laptop is turned on.
I tried accessing System Restore from SafeMode, but the System Restore screen is just blank. No options were provided.
Now I access the internet and use my laptop on SafeMode.
Is there anything else I can do besides restoring the pc back to it's original factory settings?
Help please....

Your subject title is NOT correct.

Your laptop IS booting up, and the hard drive IS seen by the bios as being bootable and having an operating system installed on it, since you're seeing the Windows screens.

Your problem is Windows is not working properly.

You have data problems on your Windows partition on your hard drive.

Either your hard drive is failing, or there's nothing wrong with it but the data on it is corrupted.
Laptop hard drives never have a warranty period longer than 3 years, and they are more easily damaged than desktop hard drives, e.g. if you dropped the laptop.

Test your hard drive first.

Check your hard drive with the manufacturer's diagnostics.
See the latter part of response 1 in this:

If you don't have a floppy drive, you can get a CD image diagnostic utility from most hard drive manufacturer's web sites, but obviously you would need to make a burned CD, preferably a CD-R for best compatibility, on another computer if you need to.

Seagate's Seatools will test (almost) any brand of hard drive.
Do the long test.

The bootable Dos versions of SeaTools can be used even if Windows is not working properly.

If the hard drive itself tests okay, any data problems found can be fixed, one way or another.

(Only the Windows version of SeaTools can test a hard drive that's inside an external enclosure - an external hard drive.)

If the hard drive itself is okay, try running CHKDSK /R

If you can run it in Safe mode , do that.

Start - Run - type: cmd (click on OK or press Enter)
Type: CHKDSK /R (press Enter)
Answer Yes to the question.
Restart the computer - CHKDSK / R will run at the beginning of Windows attempting to load normally the next time you boot the computer. Don't press any keys while you see the text about CHKDSK wanting to run.

(When you don't type a space and a drive letter along with a colon character after CHKDSK /R, it automatically checks the drive letter of the partition Windows is running from.)

If that's successful, Windows will Restart automatically, then you see a message about CHKDSK, then if you're fortunate Windows will load normally, fine.

If that's not successful (CHKDSK did not finish running or would not run) .....

If you have an XP CD or can borrow one, boot the computer from it, load the Recovery Console, then run CHKDSK /R.

NOTE that most HP and Compaq computers that originally had XP on them came with a "Windows XP Home (or Pro) Re-installation CD" or similar when they were new. That CD can be used the same way as a Windows CD, but probably only for the computer model it came with, when it's used for re-installing Windows from scratch or running a Repair installation of Windows procedure.
You should be able to run CHKDSK from the Recovery Console of any full version XP CD (except, possibly, an XP Pro 64 bit CD - all other XP versions are 32 bit).

For more info,
see response 11 in this:

starting at, scroll down to "If that won't work....."

If you don't have and can't borrow an XP CD, remove your hard drive (disconnect tjhe AC adapter's connection and the battery BEFORE you do that) and connect it to another computer that has Windows running on it, such that the way it's connected and/or the Boot Order settings or similar in the bios Setup of the other computer are NOT booting that computer from your hard drive.

Note that if you connect it internally to a desktop computer,
- you MUST disconnect the AC power to that computer whenever you are going to be plugging in or unplugging anything inside the case
- a laptop SATA drive has the same SATA data socket and SATA power socket as a desktop SATA drive - it's easy to connect to a desktop SATA header with the same SATA data cable and SATA power connector you use for a desktop drive
- for a laptop IDE drive, the combo data/power connector header is smaller than the desktop IDE data only header on the hard drives. You can connect to a desktop IDE data cable and a desktop larger molex power connector if you use an inexpensive laptop IDE/power to desktop IDE/power gender adapter, available locally. The laptop drive is set to master by default if it has no tiny jumper on two of the four pins the laptop combo IDE/power connector does not connect to on one side - if there is another drive on the same IDE data cable, it's jumper setting on back of the desktop IDE drive must be set to Slave, or just connect the laptop drive to a data cable by itself.

Run CHKDSK /R (drive letter): on your hard drive's Windows partition.

The drive letter assigned to your Windows partition on your hard drive on the other computer will NOT be C - it will be the first drive letter that was available alphabetically.

E.g. if it is G

Start - Run - type: cmd (click on OK or press Enter)
Type: CHKDSK /R G: (press Enter)

When CHKDSK has finished running, remove the AC power to the other computer, remove the hard drive from the other computer, when the AC adapter connection and battery have been removed, connect your drive to your computer, plug in the battery and / or the AC adapter, and try booting Windows normally from your computer.
