Cannot access or boot encrypted drive (gave up waiting for root device...)

Cannot access or boot encrypted drive (gave up waiting for root device...)
I cannot access or boot from my C drive. I'm running Zorin 9 and the drive is a Samsung SSD. The disk was encrypted on install, and that has not given me any problems before.
When I start the system it gets to the memory test page, and does not then load the password prompt, which it used to. I can go to password manually by pressing "Enter (Boot)", but it does not accept correct password. I have tried cap lock. I know keyboard is good, I have tried wired and wireless keyboards. I checked the disk recently with GSmartControl, and it passed with no comments. Upon attempting password I get "cryptsetup failed". After several attempts I get an error "gave up waiting for boot device".
When plugged into windows externally, this drive with the data I want doesn't show up in the drive list as searchable, but it does show up in "safely remove hardware", and in drive management. In drive management, it shows as 2 partitions, both reporting as healthy, one at 243mb, the other at 232.65gb. The drive is formatted to ext2, and with windows drivers, the smaller partition (with grub) displays in drive list, but not the data partition, formatted to raw.
Questions:
1) Does this seem most likely to be a software or hardware problem?
If a software problem:
2) I noticed that it lists the OS it is looking for as being on sda5_crypt, not sure how there could be 5 partitions on that device (it's only 250gb) unless that is part of the encryption protocol. I never noticed the partition designation before, the only thing I put on that drive is the OS, I never manually created any other partitions. Could it just be looking for the wrong partition? Is there a way to check this?
3) Is there a way to repair the boot sector, change the encryption key, or reinstall the OS from DVD without booting up, AND preserve all existing personal data? (fortunately, there's not that much on this drive)
4) I've been thinking of moving from Zorin to Ubuntu OS anyway, and my first thought was that this is an opportunity for that. Is there a way to install Ubuntu and preserve the data?
If a hardware problem:
5) Is there a way to back up and salvage the encrypted data on this disk?
Thanks for any help!

grub-install.unsupported
GRUB-INSTALL(8) FSF GRUB-INSTALL(8) NAME
grub-install - install GRUB on your drive SYNOPSIS
grub-install [OPTION] install_device DESCRIPTION
Install GRUB on your drive. -h, --help print this message and exit -v, --version print the version information and exit --root-directory=DIR install GRUB images under the directory DIR instead of the root directory --grub-shell=FILE use FILE as the grub shell --no-floppy do not probe any floppy drive --force-lba force GRUB to use LBA mode even for a buggy BIOS --recheck probe a device map even if it already exists INSTALL_DEVICE can be a GRUB device name or a system device filename. grub-install copies GRUB images into the DIR/boot directory specfied by --root-directory, and uses the grub shell to install grub into the boot sector. The grub source distribution carries this script to ease the installation of grub as a boot loader. In Suse Linux however, grub installa- tion is much better handled by Yast; use of this script is generally discouraged and therefore unsupported. Consequently, the script has been renamed to grub-install.unsupported. In order to (re-)install grub for the currently running system, simply use Yast. For an installation aiming at a differing system, the crafting of an appropriate device.map and grub shell script is strongly advised, e.g. "grub --batch --device-map=target-device.map < tar- get-grub.conf" SEE ALSO
The full documentation for grub-install is maintained as a Texinfo manual. If the info and grub-install programs are properly installed at your site, the command info grub-install should give you access to the complete manual. grub-install (GNU GRUB 0.97) May 2005 GRUB-INSTALL(8)
