|Windows Setup sometimes gets "confused" about hardware. |
If you have anything plugged into USB ports that did not come with the computer that is not necessary to run Setup, unplug it /them.
WAIT until the hard disk activity led has stopped lighting up for a while, or if never stops blinking, WAIT a while.
If it's still stuck in a loop...
Shut down the computer.
E.g. hold the power button down or in until the computer shuts off.
If you have anything else plugged into the computer externally that it did not come with that is not necessary to run Setup, unplug it .
Boot the computer.
DO NOT press a key while booting to boot from the Recovery disk - it should load automatically.
Setup MAY resume from where it got "stuck" and finish properly.
(If you press a key to boot from the disk while booting, after the first time you booted from the disk, the Recovery (Setup) process will start from the beginning again.)
If that doesn't help, unplug everything plugged in externally into the computer that it did not come with that is not necessary to run Setup. If this is a desktop computer, if you have added any cards in slots that did not come with the computer, remove the AC power to the case, unplug it /them, restore AC power. .
Try booting from the Recovery disk again.
