Idea Centre K410 boots to cmd prompt only

Question

Hi, I'm trying to fix an IdeaCentre K410 with Windows 8 on it.  The issue is when I power on the computer it does the following:
1. the "lenovo" logo comes up
2. the system beeps once as the logo disappears
3. the logo comes back after the beep
4. a circle of dots starts spinning under the logo
5. a blue (maybe bluish-green) box appears for a second or two (literally)
6. cmd.exe pops up
The command prompt starts out with X:\windows\system32>
The C: drive has been reformatted so windows is no longer installed on it.  The X: drive (I'm guessing this is the recovery partition?) appears to be intact as the X: directory contains OneKey, Program Files, Program Files (x86), Users, Windows, and LRSBootTmp.log
I've moved into the OneKey\main directory and attempted to run LRSBoot.exe (assuming this is the Lenovo Recovery System) but it pops up an alert box with the title "Caution" and then says "First parameter format is not correct, as X:XX.vbs"  I have absolutely no idea what that means.  The only thing I can do at that point is click "OK" (the only option) or hit the red x; both of which take me back to command prompt.
I was also given the Lenovo Start Recovery Discs that came with the computer, but there is no option to boot from the cd/dvd drive.  I've gone into the BIOS (the only other thing I can get into besides cmd prompt) and looked at the boot settings but the only options I get are Auto, UEFI Only, and Legacy Only.  I've tried all three.  I've also checked the "Secure Boot" status but it is disabled and I don't seem to even have the option to enable it (though everything I've read says to leave it disabled).
I've put the recovery disc and went through the various directories (in cmd prompt) trying several executables that looked like they might start the recovery program.  I get told every time that, "The subsystem needed to support the image type is not present" or "This version of..." insert file/executable here "...is not compatible with the version of Windows you're running. Check your computer's system information and then contact the software publisher."
I'm at a loss what to do.  I've never encountered a BIOS that didn't have a boot from cd/dvd option.  Nor have I ever had a computer that only loads up exclusively in cmd prompt.  Any help would be much appreciated.  Thanks.

Answer 1

Ok so I solved it after several hours... Remind me never to buy a Lenovo computer or quite possibly Windows 8.
For anyone else experiencing the same type of issue here is what I ended up doing.
I pulled the hard drive from the Lenovo computer and hooked it up to my personal desktop.  I then ran diskpart.exe in the Run window (Windows key + R, or should be at the bottom of the start bar).  I used diskpart to delete every partition (including the "hidden" ones on the Lenovo hard drive; this included four partitions labeled "Recovery," one labeled "OEM," one labled "ETFS" (or something like that, I should have written it down), and the C: partition.  Once I had a completely unpartitioned unformated drive I used diskmanagement to format the drive using NTFS. Disk management is found by right-clicking the My Computer or Computer icon and clicking on Manage: this pops up Computer Management and Disk Management should be one of the options in the left-hand pane.
Once this was done I shut down my computer, unplugged the power cable, disconnected the hard drive and then put it back into the Lenovo computer.  At this point I went into the BIOS settings on the Lenovo computer and reset them to factory default, with a slight change to the boot priority (I made the DVD drive the top priority, not sure if this was necessary or not).  I then inserted the Lenovo recovery disc 1, and allowed the computer to boot.  Since it could no longer find any remnant of the previous Windows 8 installation it quit trying to boot from the hard drive, and instead booted from the CD.
Then I just had to wait (about 2 hours) for the whole recovery process to complete and pay attention to when it asked for the next recovery disc--which I don't think it actually used discs 4 or 5 but I put them in anyways just to have it immediately tell me to move on to the next disc.  Disc 6 did finish the process however so no complaints.  Once the discs were complete it started unloading files in several cmd prompt windows and seemed to be stuck for most of the 2 hours at this point. However, a few of the cmd prompt windows are minimized and if you maximize them you will see it is working you just need patience.
After it was all said and done I created the profile and checked for windows updates about 20 times (an exaggeration but not by much) and voila it now works.  Windows 8 is back on the computer and everything is running fine.  And to top it off I didn't have to call and deal with the Lenovo support.
That said I'm not sure this is the best approach and if I had realized how screwed up the computer was I probably wouldn't have offered to fix it.  I don't recommend this approach unless you really feel comfortable in what you are doing or have nothing to lose.  Anyways thought I would share as in most cases there are several other people with the same problem.
