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.

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]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect

check this too for more info :  http://tinyempire.com/notes/ntldrismissing.htm#What_if_none_of_the_options_worked?
-----------------------------
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

Too many email signature changes to deal with?

Are you constantly being asked to update your organization's email signatures? Do they take up too much of your time? Wouldn't you love to be able to manage all signatures from one central location, easily design them and deploy them quickly to users. Well, you can!

arrg firefox 4 locked up...

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
