I'm using Dell Inspiron 1420 with Windows Vista Home premium. 2 weeks back installed Windows7 as dual boot on to my laptop. I installed it in a new way as my CD/DVD drive is not working. I extracted the Windows7 iso file into a folder and then double clicked on the setup file. The a series of dialogue boxes which pop up for normal installation appeared and done, I got Windows7 dual booted onto my laptop.
Now I'm trying to install Windows XP in the same way, as I don't want to use Vista due to compatibility reasons. But when I double click the setup file in the extracted iso, all the options except Install Win XP are working. I tried many times but the option is disabled. Please help me with this. I'm badly in need of XP. Thank you.
