MBP install questions

hi their, can somebody please help us,
i have just replaced the HDD for a new one, and formatted the hdd to journal ect, and copied time machine back up to the hard drive
now is it possible to get the osx from that back up, or do i need original install discs, its for a friends mbp and he doesn't have the discs with him, but does have a full up to date lion osx but how to install that, ?
please any help would be nice

 

As the Time Machine backup is not bootable, copying the backup to your new HDD will not work.
If you still have your old HDD, just put it into an enclosure for 2.5" S-ATA HDDs and clone the contents of the old HDD to the new HDD.

If that does not work, you can get replacement DVDs for your Mac via Apple.
Or if your Mac came with 10.6.2 or lower, you can buy the 29 USD Mac OS X 10.6 Snow Leopard Upgrade DVD.
Or you can buy the 69 USD Lion USB Install Thumb Drive.

As for using Lion from your friend:

 

if i use a snow leopard update disc will i be able to install that, and then get to the app store, and get the lion that is already paid for, and then download, install, and then run time machine back ups.
the hdd was replaced coz it is faulty, i do have a tech tools disc, with cloning on it, so i will give that a go, if any life will come from hdd, if not.
when he gets home, and finds his discs, is it that long old install, to get back to lion, or is their a short cut.

 

Yes, while tedious, it will work.

Next time make an installer of Lion onto a USB flash memory thumb drive.

thanks for that, installing SL and gonna see where that takes us, we are snowed in at the moment.

 

And after you install Lion over SL I'd recommend using setup ass't to migrate over your stuff since it's less likely it would bring over something that got corrupted.
