|If data recovery is your prime concern at this moment - and it would be mine...|
Go to ubunto.com; download an ISO for ubuntu (a freebie Linux variant); burn it to a dvd; boot with that dvd. It will load itself into RAM only - and will NOT touch the hard drive or install itself there (unless you opt to - which of course you won't...).
You can then access the hard drive in your Toshiba and copy "anything" you wish to preserve in terms of "important stuff" - files etc. Copy them to dvd; and if possible to an external hard drive as well. Verify the copies are accessible on at least one other working system too - to be sure they're OK.
Then set about resolving the issues with the XP boot - knowing your files are safely secured/copied elsewhere.
There are websites where you can download an XP ISO - legally. Don't have them to hand just now - but others here will likely popup with them for you.
Download the OEM version (and burn it to a dvd) - as likely that's what is your Toshiba has installed.; a retail will not work on this occasion. Might as well get the retail version too - just in-case you do have a retail installation and not an OEM. You use OEM with an OEM software installation; and retail with a retail software installations...
You can boot up with the dvd you have made for XP and then try a few options that way - of which more anon... If an XP key is required - and you have an OEM installation - you can use your own (OEM) key; and of course if your Toshiba has a retail installation then again use your key with a retail ISO/disk. That key (whichever it be) will likely be on a sticker on the base of the laptop?
Also - possibly you have been hit with a pest... So with this possibility in mind... go to the Kaspersky rescue disk site; download the ISO; burn it to a dvd; boot with that dvd. It will (being based on aLinux OS again) load into RAM only; then it will go on-line to update itself. After-which it will scan fully the hard drive (if you opt to - and I would); and it will fix anything nasty it finds...
Perhaps run the Kaspersky utility first - so as to hopefully remove anything nasty fist - that "might" otherwise go over with your personal files in safe storage...
Kasperksy utility is "free".
If having recovered/safeguarded your files (and checked the external copies are OK ) and you are OK with a possible Factory reset/restore routine, then you have that option too - anon. Also with a suitable XP installation disk you likely can effect a repair installation... which will (barring accidents...) preserve the current installation as is - but will require a download of some (at least) of the updates. A repair installation in effect overwrites much of the current installation; it is NOT done via the Recovery Console - post back for more on that if needs-be.
Get both the sp2 and sp3 ISO versions; as if your Toshiba installation is not currently sp3 then you will have to use an sp2 ISO (XP disk); if it's sp3 then you ought to be able to use an sp3 ISO (disk).
If you have anyone locally with a XP suitable disk - you can use that - and also make a legal copy of same; as you will be using "your" installation key - "not theirs" - for all use of the disk.
But before going through any form of repair routine - first safeguard your personal files etc... as above!
