Equium L300 - Can I use Recovery CD from a other Toshiba notebook?

Question

Hi,
I can't get a computer to load Vista (Equium l300 I think).
Ubuntu loads just fine (I have an 8GB linux partition, with GRUB installed in a separate partition), but when I try to load vista I get "Starting..." and nothing happens.
I tried HDDRecovery pressing '0' or 'F8', but that gave me a disk check for errors and nothing more.
I still have a backup from HDD recovery in another partition, but I don't know where to place it, can you tell me where?
Then I found out I have a toshiba recovery disc from my wife's Satellite.
Can I use it to recover the Equium or will it erase it's genuine Vista installation putting a new 'pirated' copy in it's place?
If I can't, can somebody tell me where to place the backed up HDDRecovery image folder?

Thank you Horwath, but I was not attacking Toshiba in any way whatsoever, since that will not solve my problem nor spare my time. But now I feel like the prevailing attitude in this forum is becoming an issue worth commenting.
Saying +You should have done this and you should have done that+ is even worse than RT#M, because RT#M usually applies to something that +can still be done+, while telling me I *should* have made a copy before is something I *already know* and does not apply to the present situation. Also, just keeping a recovery medium is not enough since home burnt CD's often peel with time (at least in hot wet climate areas they do). So asking how to safely edit the partition table without affecting the recovery partition is very pertinent question in a forum such as this one.
The problem is when I do thoroughly RT#M, and instead of telling me how to keep the recovery partition safe from damage, the manual just tells me not to edit the partitions at all. Even worse, it tells me not to edit the partition table in a manner not recommended by the user's guide even though *there is no recommendation about partition tables in the user's guide to start with*.
When the manual doesn't give me all the information I need --- And as Horwath correctly implied, they never will because they shouldn't --- I turn to user fora. Now the real problem begins when all I can get from the user forum are the very same legal disclaimers I find in the manual. In no other user-to-user forum I get that kind of attitude.
Actually, this doesn't look like a user to user forum at all!
I *don't* want to blame Toshiba for it. Toshiba products are great, and I have two Toshibas at home because I recommended them to my closest relatives and in laws. As soon as my 5 year old Dell starts aging (and it still hasn't), I will think of buying a Satellite for myself and I will create a recovery disc. *But that's just not what I have at hand now*.
What's missing is just a clearer and more objective communication. And by objective I don't mean +click here and buy a new recovery CD+.
