How can i get my XP back

Run msconfig check boot tab, see if XP is on list
If not download & run easybcd to edit boot files to include XP
Theres a tutorial for this somewhere will post link shortly

Ok cant find tut
Run easy bcd
Click on Add/Remove Entries
Under Add an entry at the bottom click Windows NT/2k/XP/2k3
Then under name type Windows XP (or whatever you want displayed in boot manager)
You may need to point it at the drive XP is installed on but it normally does this itself
Click Add Entry then Save

See tut below for the rest

i had windows Xp earlier. i installed windows7 alongside XP but after the installation i obtain no booting options or any booting screen for OS selection. windows 7 is default OS and boots directly.
How can i get my XP back without removing windows7.
i jumped to windows7 directly from XP.
i installed windows7 on separate partition.My explorer shows the existence of both the windows folders in separate partition.

Take a look at this tutorial on how to install a dual boot. Dual Boot Installation with Windows 7 and XP
