Alright, so long story short I got this laptop out of a junk box of old electronics at work. Perfect condition, but no hardrive or power supply. Easy to find online and order.
I installed the new hardrive and plugged in the power supply. Yay it boots up!
Then I get a black screen with a note at the top "No bootable device"
So I do some Googleing and try all the fixes that are suggested, I remove and replug in the hard drive, I reset the BIOs settings, I make sire the hardrive is at the top of the boot up presses and I ran a hard drive diagnostic in BIOs. Nothing.
I would love to get this little laptop running so I can bring it to DND games (my usual laptop is twice the size of this one and a bit inconvenient, please help!
