Problem: Bootup begins by powering on. Toshiba screen displays. "Press F2 for system utilities, press F12 for Boot Menu." as usual. should usually go to a windows XP Home loadup screen. Instead, the screen goes to a black-and-gray console screen, with the letter "j" and a flashing cursor in the top left. The only keys that do anything from here are Ctrl-alt-del, which restart the same process from the Toshiba Screen.
System Utilities or Boot Menu doesn't seem to help. I know I want to boot from the HDD. I select this and it still ends in an innocuous letter "j" and no signs of further booting. All the components seem to be present in System Utilities. My HDD is definitely there.
Upon Googling "bootup letter j" I find that this is most often experienced when you're booting Windows or Ubuntu from a USB stick, both of which seem exotic to me. We're just booting Windows XP from the HDD same as we have.
Changes made before the problem: None major. A new external power adaptor (the usual box-and-cord) was put into use 3-4 days before the problem showed up. Some unused personal files were deleted two weeks ago, clearing about 10% of the hard drive. That's about it.
Any ideas, and anything I can further provide?
I think some other people have had this problem. If a fix is provided here it'd probably be referred to by a lot of thankful people.
