Please excuse me jumping in with a question (I'm curious, in no way queerying the advice):
*As GRUB was the Bootloader whilst JakeLogan was Dual Booting with Windows 7; (presumed)
I take it that once the step; "Delete the Linux partitions" is completed, GRUB no longer exists, and with first reboot, > then CHKDSK >, Windows restores it's MBR (master Boot Record) ?
*Then booting into Windows there is no trace of GRUB, just a boot to Windows Login screen?
( I used to do something slightly different, restoring the Windows MBR)
Thankyou for clarification,
