Damaged NTFS Boot Sector: Win 7, Win XP Dual Boot, A Disk Read Error, Invalid Partition Table

Hello,
I had win 7 and thought to install Win XP on the second partition. Everything is good, only the internet in XP wines did not work and 7 already did not want to turn on. I formatted the XP wine partition because I thought I wouldn't need it. When I wanted to reinstall win XP, I only got one partition 153/153 GB free, I installed it and after the reset the error A disk read error occurred. I connected cables to other inputs and an Invalid Partition Table popped up. I put it in place and then the same. I started with full instalke win 7 because the drive does not work and I gave the system a repair, which did not work. In addition, the installation does not detect the disk at all, it says that it is unknown. Fixmbr command does not work and fixboot cannot find a file. I tried chkdsk with commands to no avail. You can see the disk normally in the bios.

Specs:
AMD Athlon x64 dual 2.01ghz 3800+
Gigabyte board I don't know the model
1GB RAM
WDC WD1600YS-01SHB1

I will add that chkdsk says that the NTFS boot sector is damaged. I can't check the disk with someone, play testdisk and this type of dupes for pen, change SATA cables. I would like to fix it myself, but if it is impossible, I will contact a specialist

Hello,
your description is a bit unclear for me, correct me as I think:
- you had win7 and installed Xp on a different partition but boot sector on C so xp overwritten the win7 boot sector.
- you formatted the entire disk so you shouldn't have anything on the disk anymore, neither win7 nor xp except recovery if it was.
- "I installed on it and after the reset an error A disk read error occurred" - but what did you install? you have an error in floppy drive A? and what did you use it for? additional SATA drivers for XP?
- You are repairing an incomplete system so it won't work.
- the installer did not detect the disk? and what did you do with him, check the connection errors - does the bios see him?
- fixmbr and fixboot are OK but if you have a system on disk installed and yours is severely incomplete after your run and what file it doesn't find - this might be a hint.
- check the SMART disk, maybe it is already starting to break.
- It will not do without another computer or booting from USB, I would take the disk under some live linux and possibly repair the MBR or partition tables but this is associated with a total loss of data from the disk.
If you do not fully understand my description, maybe ask someone for help
greetings

I had 3 partitions: with win 7, files and 3 are win XP. I formatted the partitions with XP wines but later read that the internet might work, so I wanted to reinstall it and then it all happened. From the 3 partitions, one has become one, i.e. it has been removed as if all of them are installed on this empty one, the BIOS can see it, connected well.

Added after 5 [minutes]:

He now writes a disk read error occurred again

Hello,
burn some linux live (suggests Linux Mint is the most similar windowso) see how the SMART disk looks like, if it's OK then in Gparted options you really have MBR and Partition Tables.
Your data is no longer on the disk, they are physically there, but access to them is not possible.
greetings

I care more for the disk to survive and I care little about the data on it. Recordings of this Linux. Does he need a disk or not to run?
E: this is the partition where the XP win was, it is 153 GB and I gave 15 GB ac: it was from win 7

It is not true that repairing a partition table involves data loss. The same use of a new non-sponsored partition does not delete data. We don't know exactly what the author did and the description is a bit chaotic. You can run, for example, DMDE under Linux and check what happened, what the partition table looks like and what is on the new partition, whether it has the boot flag, etc.

Good problem solved. It was enough to format the disk and create the partition from scratch. I have installed W7 and everything works. Thank you for your willingness to help. I close.
