I Have a backup dis while I lost the original dis....
The original discs are machine specific. Reason why you need them. Backup disc will not work.
You can get replacement System Install & Restore CD/DVDs from Apple's Customer Support - in the US, (800) 767-2775 - for a nominal S&H fee. You'll need to have the model and/or serial number of your Mac available.
Since you're not in the US, you may need to go through the regional Apple Store that serves your location to find the contact number. Here's a list of links to all of those - http://store.apple.com/Catalog/US/Images/intlstoreroutingpage.html Another resource: International Support Phone #s.
should I consider pay for someone to fix it?
