HP Laptop stuck in loop.
I have a HP laptop that is stuck in a boot loop. It get to a screen that says "press the esc key for startup menu" then a cursor in the top left corner and..... reboot. It is a pavillion g6. Also, I have tested the HD using Hp diags and it shows good.
Can you test the memory? If you can, remove one memory module (or 2) and try starting. Same issue, or not?
The PC manufacturer's diags are usually not reliable. Use the disk manufacturer's diagnostics, and also test the RAM using memtest86+. The disk manufacturer's diagnostics as well as memtest86+ are included on the UBCD:

chkdsk will not necessarly discover hdd defects, it looks for errors in the structures of the filesystem but does not try to access each file by default.
same is sfc /scannow it also will not access all things necessary to boot up.
As poster above said, use the hdd manufactures tools to diagnose the HDD be careful not to choose any of the destructive tests, some of the offered test procedures will erase all files on the HDD. Usually the diagnostic software will give a warning. So if you are careful what you are doing and read all dialogs carefully you wont run into problems.
Nevertheless you should boot from CD and recover/backup all important files, that are not backed up yet, before you do any diagnostic. The diagnostic may stress the hard disk and it may fail during the test, rendering the files unrecoverable by you.

you can always hook the drive to a working system to run the diags needed - and backup before starting to repair - always wise
i also agree running the HD manufacturers diag; for most there are versions that can be run a s standalone (best) and from windows

It appears running chkdsk on it fixed it. When I came in this am after running chkdsk last night the pc booted fine. Seems odd to me. I am about to run diags on the HD to make sure it ok, but the pc appears to be fine now.

When I ran chkdsk it appeared to have fixed the problem.
Maybe your operating system on the HDD gots corrupted, this can also happen even the HDD is in perfect shape.
e.g. caused some malware or operating system crash/bug.
Can you after booting the laptop from CD/DVD access the internal HDD and see the files there?
OS and user data?
