Yes, Windows Stop code 0xc000021a can have multiple underlying causes.
Windows support is off-topic for this board. I know that may not be what you want to hear, but it's best that you have realistic expectations.

You haven't said what CD you were trying to boot from, and whether it was known to be bootable (not all CDs are bootable) - but in any case, not booting from the CD cannot be due to a hard disk fault, so you'll need to find out what else with your system is causing you not to be able to boot from CD.

Provided you have successfully copied the data off the
original hard disk and it is now safe, then that is the end of any hard disk concerns, isn't it? If you have hard disk problems, please explain them clearly and in detail.

Unless you have a problem with a hard disk, then your request is off-topic for this board (unless a member volunteers to help you privately via PM). If you're looking for general computer or Windows support, you may want to ask friends/relatives for recommended local support providers close to you. Good luck!
