This question already has an answer here:
I have installed Ubuntu and thought I dual-booted it... But I didn't, so now I wanna go back to Windows (I have a Windows 8 CD) but when I insert the disk into CD/DVD drive and change my boot menu it still boots in to Ubuntu.
I installed Ubuntu over Win7 Home Premium using a LiveCD, it's said that no filesystem was recognized on my laptop, so I thought it was automatically placed on the unallocated partition that I've created. But it didn't, so it just deleted my Windows partition and installed Ubuntu on it.
What is the problem and how can I solve it? Thanks!
EDIT: I don't know much about computers but i just got this hp pavvilion dm1 whit windows 8 isntalled on it and updated it to 8.1
i installed ubuntu the this way: making a new partition, and making the swap and boot or something my self by clicking ''something else"
ps: i don't have a dvd drive
