"No hard drive installed" error after reboot

[carolanderson]

all of a sudden my laptop stopped working.  when I rebooted, it said no hard drive installed

Turn OFF the Notebook and once its powered ON, keep Pressing F10 to load BIOS screen of the Notebook. In this screen under Diagnostics, run the test on hard drive and memory. Post back the results here.

Also in startup menu there is an alternate way where you can run F2 (System Diagnostics). The instructions can be found at below link

I  hit the f10 key several times on startup, and the problem was solved.  Everything came up just fine.  thank you so much!!!

what do u do when it says harddisk does not exist??

[carolanderson]

I restarted it and pushed  f10 several times while it was booting up.  don't know if  it's the right thing to do, but it fixed it.

i did tht and it went to the page and it wouldnt let me do one of the tests because the hardisk doesnt exist and i am wondering how do you get the hardisk to appear

[carolanderson]

I don't know.  Mine just went back to normal from pushing f10.  I didn't have to even do the diagnositcs.
