If the original hard drive reflected a recovery partition...and you cloned the drive...the new drive has such.
If you did not clone the drive...and your Acer disks don't reflect the recovery partition...then you have erred.
If you did a clean install of Win 7 with a license/disk other than that supplied by Acer...there is no need for a "recovery partition", since such exists only as a substitute for reinstalling Windows to the state that it existed when system was first purchased.
System Restore is the Windows function provided by Microsoft for system problems.
What you need to be doing constantly/routinely...is backing up your system.
