Windows 7: How do I use disc image created by Acer BackUp Mang?

I recently had computer crash and system restore not work. I have two files on an external hard drive (BackUp 30-10-11 2011-10-30 15-35-33_C.CAL and BackUp 30-10-11 2011-10-30 15-35-33_C_1.NBF) that were created by Acer Backup earlier that I wanted to use but can not seem to get the program to run properly. If anyone could please let me know step by step how I can do this I'd greatly appreciate it. I'm afraid the "help" is not overly so...

hi sorry to hear you have problems check this link out its for acer support there are a number of links you can choose that should help you Support Home Page if not post back and i could help you your machine

Using Acer eRecovery Management to reinstall Drivers and Software >>> http://goo.gl/91qLs

Will try back in a bit either way....

Nothing there to help... the above two files were made when I thougth I was creating a disc image for my computer but can not seem to get them to work... when I open acer backup manager and select "restore" it asks me if I want to let the program make changes so I select "yes" and a new window opens....
In the "Restore" window... nothing happens if I click on "Disk Image" top right corner...
In the "Source" box if I click on "image I'm able to navigate to the external hardrive (in my case H:\) where the file.... "BackUp 30-10-11 2011-10-30 15-35-33_C.CAL" is the only one of the two that shows and if I select it....
This shows up in the "Source:" box... BackUp 30-10-11 2011-10-30 15-35-33_C...
And in the window below "Restore Point:" under date the date as above shows witht the time 14:35 and 180.66 GB size....
But the "Destination:" seletor tab does not allow for me to make any selection as I would wish ie the "C:" drive

Now if I click the "Restore" button on the bottom nothing happens but if I hit return it just shuts off the program...

What am I doing wrong....

i had this problem with a desktop pc a packard bell( which acer now own) there restore did not work so i made a recovery disc for windows 7 have you one of these?

you normally have your back up oem files on the main hard drive in a partition like d or e

I made a three disc backup disk set on dvd's if that is what you mean as well as single "repair disk for windows 7 64 bit at the same time

is your machine booting into desktop?

Yes I have the acer desktop which is the unit with the issue as well as a mac laptop which I could use for communications if need be to fix the desk top

cool go here and see this tutorial by brink System Restore - Windows 7 Forums read it and choose option 2

Cool... I'll give that a try and get back to you...
