2.) The procedure wherein you lot postulate to re-create linux configuration on c: drive of Windows together with edit boot.init.

What worked for me:
1.) Install Windows 7.
I possess got 500 GB (sda) together with I divided it into four partitions:
sda1->Reserved partition
sda2->NTFS, Windows vii partition
sda3->ext4, Linux partition
sda4->NTFS, Another logical extension for dorsum upwards files

 Things you lot should accept note, I install Ubuntu inward my ext4 segmentation together with the kicking loader inward the principal drive: sda without whatsoever number.
