I recently got a new laptop from the US. I've used desktops all these years, and know how to format, backup and recover data, but haven't used a laptop before.The laptop is a Toshiba Satellite L 755. Earlier it had three partitions as shown in Administrative Tools > Computer Management. The first was a 1.46 GB one, shown as "Active, Recovery Partition". The second was C: drive, around 590 GB "Boot, Page File, Crash Dump, Primary Partition", and the third was around 14.5 GB. Only the C: drive would open, the other partitions wouldn't open at all.I'm not really sure but these were recovery partitions, and what I did was I used Paragon Partition Manager to split C: drive, so that now there are three partitions: the first is the same, the second is C: drive with 297 GB, and the third is E: drive with 297 GB, which I formatted with NTFS.It seems I messed up the recovery partitions. What I would like to know is whether these are really important or not, and what they contain. Can't you use a laptop like a desktop, changing the partitions as you like, and installing the drivers directly?When the laptop boots up, there's an option to press F12 and return the computer to its out of box condition. There are also five or six recovery DVDs.
