Re-install OS using the Install CD bundled with the laptop.
You can probably download phone apps to a standard laptop, but they won't be able to run because the laptop CPU and OS are incompatible with the smartphone CPU and OS that the apps were coded for. But if you had them on the laptop and then downloaded them from the laptop to the smartphone, they would run on the smartphone.
well i never tried it but what you may have to do is write the OS on an other computer by linking the harddrive of the laptop to a computer with a CD ROM drive. afteer you write the OS on the harddrive you place it back on the laptop with no drives.
You can't. You need a Mac.
Apple's Mac OS X 10.6 (Snow Leopard) can be installed on an Intel laptop if the laptop is made by Apple.
Go to Microsoft website and download this file 'WinXP_EN_HOM_BF', extract it and follow the instructions to purge your laptop so you can install XP Home Ed. This will completely wipe your laptop clean and you can begin with the new OS. PS: It is asumed that the word 'reformat' defines as formatting and installing a new OS. Otherwise, turn on your laptop, eject the CD player, turn off laptop and just put in the new OS and turn on again. Follow the instructions. It should overide any old OS. Warning: Be sure to have a backup of all your personal files.
