How to restore boot disk?

Question

linux

There are two disks in the computer: on the 1st (51 GB) there is Windows 7, on the 2nd (465 GB) I installed Linux Debian.
I needed Windows, but when I tried to boot from the first disk, I got an error: MBR error 1.
I booted from the installation disk, entered in the console: bootrec.exe /fixmbr.
After that, when trying to boot from any of the disks, Linux began to boot.
1. bootrec.exe /ScanOs detects Windows 1 thing.
2. Further bootrec.exe / RebuildBcd, but when I try to add the detected system to the boot list, I get: "Element not found."
3. diskpart list disk gives out only two disks, there is no boot disk (100 MB).
I really ask for help! Do not reinstall now?

Answer 1

Problem solved.
1. Booted into Linux (Kali), opened the GParted disk utility, noticed that only the disk on which Linux is installed has a flag (flag) boot, which boots in any case, no matter which disk I choose, as bootable.
2. I set the boot flag for the disk with Windows
3. I rebooted the computer
4. The MBR error 1 error disappeared, the BOOTMGR is missing error appeared.
5. I inserted the installation disk, booted from it, selected the "System Restore" item, waited for the system to automatically find errors, clicked "Fix and restart"
6. BOOTMGR is missing. Great, Windows 7 appeared in the "System Recovery Options" window, selected it, clicked "Next", followed. window - "Startup Repair".
7.
If it doesn't help, then here is the page . It has a section called "Restore normal Windows boot using Hiren's Boot CD".
You can also try the Grub bootloader.
Installing on Linux is elementary:
Format the flash drive (file systems: ext4, ntfs, xfs, btrfs, vfat).
0. sudo mkfs -t ntfs -L FLASH /dev/sdc1
1. sudo grub-install /dev/sdc1
The name (sdc1) can be found in the same GParted, for example.
Next, we generate a configuration file so that the installed operating systems are automatically detected.
2. sudo grub-mkconfig -o /boot/grub/grub.cfg
I hope that this helped not only myself. ;-)

Answer 2

You need to boot from any Live cd, check for the presence of a Windows boot partition. Check that this section is marked active.
Next - in the BIOS, we set the boot only from the disk where the Windows are and look at the error.
