How to solve the partition problem of the installed system and the partition error of the reinstalle

Dual system installation should be from high to the bottom,It is recommended that you put Win7 into the C disk first,Then put the XP on the D disk,Now ignore these,Solve your problem first。 Because I only know your general situation, I will give you two methods, from your description, I know that your problem should be caused by the error of creating a D disk to install the system or the installation environment is unstable during installation, resulting in reboot or error, resulting in the corruption or loss of the partition table.

Method 1:You**This hard disk partition software Acronis Disk Director Suite,To English version,The Chinese are not original,It's not good,Online library has its tutorial,You can go**,This software is very powerful for hard disk repair and partitioning,I've compared,It should be very good,Extremely humanized,It won't damage the files stored in your hard disk,I don't evaluate the pq you use,I can only say that for non-professionals, Some of it is not perfect enough, and it is easy to get your information and documents if you don't use it well. (Waiting for it to become more stable and powerful),The above software is divided,4 modules,You choose to repair the module (the online tutorial is very detailed,I won't say more)。

The second method: another micro software program, diskgenuis this software you want to ** that runs under DOS, some system disks in the toolbox with, use it to restore the registry must be in the DOS environment, take the disc into DOS, and then enter the program in DOS such as: A:

I suggest you use method one: be intuitive.

Well, hope these methods work for you.

Originally, the computer had only one partition. The others are separated by magic into the system. So the system can't fit in、In addition。 You mean that you can install XP and win7. The system does not support high to low.

Win 7 Bottoms XP is not very good and easy to have problems! Only from the low-level version to the high-end loadout!

I encountered a similar problem with you today, and I replied with pq, but the things in the f drive are gone!

The partition was re-established. You can also use DiskGenius. Just look at the usage.

I also want to know how to get things back to the original.

Merge SSDs into a single partition, use the MBR partition table scheme, NTFS file system, 4K alignment, and enable AHCI mode.

In this case, when the system is installed with PE, the partition table is corrupted and the boot is corrupted due to the forced deletion of the configuration partition.

Here's how to deal with it:

1. Go to the BIOS, find the hard disk format, and adjust it to IDE.

2. Use the hard disk partition tool under PE to repair the original partition table, and then reformat the C drive after getting it back.

3. Then you can install the system normally.

4. After installing the system, repair and guide it with PE.

This problem is very simple, and this problem is often encountered under PE, after all, it is the original image file installation of ISO, which is different from the ordinary ghost system. Under PE, first extract your ISO file to any drive letter (except the C drive letter). In the files you have extracted, copy 3 files to your C drive directory respectively

boot bootmgr sources.OK Now it's more than half of the success, after that, restart, unplug the USB flash drive, and go directly to the installation interface! There is a problem here, that is, sometimes the reboot cannot boot due to formatting the C drive, at this time you can use the disk partition table under PE to repair the boot.

For example: 1. If our hard disk is now divided into five disks: C, D, E, F, and E, we want to install the new system in the C drive when we install the new system. Then when selecting the disk, click the C drive of the drive, click the selection, and then click the delete button below to delete the C drive directly.

2. After deleting, select the unallocated space that has appeared now, and then click Next to install the new system in this unallocated space to install it smoothly. At this time, the system will automatically create an EFI recovery partition of about 300MB in this unallocated space, and the system can naturally install normally with the recovery partition.

Note: 1. It should be noted that if the C drive is deleted into unallocated space, then all the files and contents in the C drive will be deleted and cannot be recovered. So make sure you have a backup of all your files before you do this, and delete them here if you're sure you can delete them.

2. In addition, remember not to use Disk Utility to delete the EFI recovery partition after successful installation, otherwise you will not be able to boot normally after restarting after deletion.

2.Solution 1: Make sure you only have one hard disk, then when you reinstall the system, delete the system disk C drive directly (remember to back up the data), and then select this unallocated disk, and the next step is on the line.

3.Solution 2: If there are two disks, you need to change the system disk in the first position of the index, the easiest way is to unplug the non-system disk, that is, the hard disk other than the C disk, and then install the system, it's OK, if it doesn't work, look at plan 1.
