Windows XP pro reinstallation failed; OS is working great now but can't install any new software now

My OS, XP Pro, was working badly. I launched the PRO cd setup from inside windows and it ran, when I came back later it had an error on the screen, black screen on the 'rebooting' portion that reported a disk error and requested to hit cntrl-alt-delete to retry. I do that and choose windows xp professional rather than XP Professional Setup, (which is a choice every time I boot up now), an unpleasant aftereffect from the failed part of the reinstall/reboot. I assume the failure is because I have an SSD hard drive in the PC, but who knows? What I want is for the 'setup' choice to go away when rebooting and for the registry to let me 'use' it freely now, to install new software (namely Quicktime, although I have tried three other programs today too and can't install adobe reader updates either as they fail too). So I believe the registry is 'write-protected' at the moment, but since the OS is working so nicely and I am happy with that outcome I would like instructions on how, through booting to a linux CD or my Bart's PE CD or recovery console, to unlock the registry so that it stops preventing me from installing new software.

I would recommend running subinacl

You will be able to install all the softwares.

Are you the administrator on the PC?
it looks like many different problems to me :
>>  xp professional rather than XP Professional Setup, (which is a choice every time I boot up    <<  you can run msconfig from the run box, and edit the boot.ini file, it should look like this :
Contents of the boot.ini file :
[boot loader]
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect

check this too for more info :
delete the extar lines (make first a copy of the boot.ini file, so you can always reset it)

>>  SSD  << is it set to AHCI  in the bios ?  the xp cd has no drivers for it, nor sata drivers

solve these 2 first..then continue
this can help too :
Free Tool: Port Scanner

Check which ports are open to the outside world. Helps make sure that your firewall rules are working as intended.

Click Start -> Run. Type this command in Run box and press Ok. REG add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableRegistryTools /t REG_DWORD /d 0 Then a prompt will come up with this question: Value DisableRegistryTools exists, overwrite (Y/N)? Type yes and hit Enter. After u did that also type this command in the run box and hit enter. REG add HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableRegistryTools /t REG_DWORD /d 0
