I sold my Lenovo IdeaPad S10 to upgrade it to a Lenovo IdeaPad S10-3. As it happened with my sister’s S10-2 netbook, the partitions scheme looks like the ones shown above: A small partition (I assume to boot Windows), a 100 GB partition for Windows 7, another partition with 30 GB for backups, and 150 GB of rescue and driver for Windows.
Because my disk is mine, I decided to erase the two last partitions (I backup-ed its content first) and change the size of Windows 7 partition in order to make room for two Linux (Debian and Ubuntu), another partition for 1 GB of swap, and the remaining for /home, as is shown in the following picture:
The only side effect is that some applications supplied by Lenovo, like the OneKey Recovey, won’t work properly because the partitions had been deleted. The solutions is to make the rescue disks before erase those partitions, or live with those partitions but resizing them to make room (this what’s I did on my sister’s netbook, a Lenovo S10-2).
Before resizing the Windows partition you better defragment the disk. You should also check that Windows 7 boots properly after resizing the partition, if not you can recovery it by using one of those partitions provided by Lenovo. I did the mistake of erasing them, so I had to borrow a Windows 7 recovery disk, because I didn’t want to wait for a recovery disc shipped from USA.
