The process i told u above is to restore the grub....anyway
I use exclusively one Linux partitioning tool “cfdisk” and use “fdisk” as a second check. Both programs are standard tools in a Linux Live CD. I specify the partition type number of 83, 82, 6, c and 7 for native Linux, swap, fat16, fat32 and ntfs partitions respectively. In using cfdisk for partitioning the partition type is 83 by default and this is recognised by every Linux installer.
