You can solve the problem of dual-system reinstallation !!!

You can solve the problem of dual-system reinstallation !!! -- Linux general technology-Linux technology and application information. For details, refer to the following section. After the incident: I have a 2 TB hard disk and a partition of about GB for the XP system. The remaining space is all extended space, and three partitions D, E, and F are created on it, then, the remaining GB of extended space is installed with the fedora16 disc. Then, after importing all the data into fedora, XP is reinstalled. During the XP reinstallation process, delete the D, E, and F partitions. After the reinstallation is complete (the boot guide for the fedora startup is damaged), go to the disk manager in windows, in the extended space, we can also see a piece of available space after D, E, F are deleted, and a total of GB of fedora partitions. This is a tragedy: after I re-created the D disk in the available space, I found that all the ora partitions I could see were missing, and the entire hard disk was less than 300 GB. A newbie is on the road. I wonder whether the hidden fedora will be able to recover from his life's painstaking efforts? We thought that rebuilding the fedora boot would bring the lost fedora back to its original shape, and various methods of searching for the reconstruction guide would not work. Most of them were about entering the rescue mode, it seems that the installation disk of fedora16 does not exist! Good luck! Thank you !!
This is the case when I re-install the partition step with the installation disk a few days ago:
LVM Volume Groups
Vg_lqreed 1807200
LV _root 51200/ext4
Lv_home 1750944/home ext4
Lv_swap 5056/swap
Hard Drives
Sda
Ssda1 99998 ntfs
Sda2 500/boot ext4
Sda3 1807230 vg_lqreed physical volume (LVM)

I have never quite understood what LVM is. At the time of partitioning, root, home, swap, and boot were all under sda. After a fault occurred, the first three partitions ran to the top, there is only one boot, and sda1 is the c disk after the reinstallation.
This is when I re-install the partition with the installation disk today:

The C drive is invisible, and the home drive is also inexplicably enlarged. All the files and materials are in the home drive. What should I do ......

Thank you !! Thank you!
