I have a somewhat old Toshiba. Satellite C75D-B7260. i was having problems woth the disk running at 100% so i tried poking around and ended up doing a restart and scan and now it would get stuck at 10% during the scan and next thing you know now it just pops up, no bootable device -- please restart system. The first time i got this laptop a few months ago i just hit 0 and did hdd recovery and it worked fine until now. Now i cant even do the hdd recovery. All it does is let me hit f12 to the boot menu and it has the hdd info but wont boot from it. Hoe can i just wipe this laptop again? Trying to keep windows but if i cant its fine.
