I have a lenovo laptop with 100gb western digital hard drive with a corrupted OS. Files still intact. What I had in a corner was an old 30 gig toshiba 2.5 inch drive. I went to a computer shop and bought myself an external hard drive enclosure. I used an ISO version of Mandriva 2008 (just because I had one), and used that to boot my computer. I installed that distro by changing the BIOS Settings on my motherboard to boot from the DVD and then installed it on the external Toshiba drive. I switched it to boot from USB. So I then had the full version of Mandriva booting the laptop from the USB Toshiba drive. I then discovered Mandriva 2008 was not supported. I installed the 2011 version which ended as well. I saw Mageia 3 ISO So I used K3b to burn that onto a DVD and installed that. I now get messages about Mageia 4. I plan to do an update this weekend.
I went to Mageia's web page since it is the home page. I choice of letting the upgrade work on its own via live update, or from an ISO Image. The live version will wipe the drive. But the ISO will do the upgrade. Mageia's page says that you can place the ISO image on a USB stick and install it from there. You can also download the Live version and burn it on a DVD or USB if you want to run it on its own without installation. You should be able to use a USB stick witht he Live version to run Mageia without full install.
With Mageia 3 I use Dolphin to access the internal Western Digital drive to recover files . IF I get around to it, I MIGHT get a Windows OS. Mageia will be my primary OS with Windows being secondary in a dual boot system.
I installed WINE for executable programs, and XDOSemu as well. This helps with some programs I still want to use from my other system.
