Dual System Windows 7 Fix 5

Use the Windows 7 installation CD, which has an item to repair the system, you can try.

It may be that your boot was destroyed when the power was off, and the office will definitely not be able to be used after you reinstall the system.

If you can't install it in win7 system, you can install it with a USB flash drive.

First win7 and then win8,The two systems can't be pressed on a disk, you try again。

If you have a Windows 7 CD, it's best to use a CD to repair it, so that in Windows 7 you can change the default system, if you can't use the software bcdautofix, I can pass it on to you.

No, the system you went under can still be used, so with Symantac recovery tool, because both. gho format, it should be easy"File loss,That should be that the system disc is incomplete,Change it,It's good,The system of the earth should be installed in that way of hard disk,It's also okay。

Other disks must be formatted to NTFS format to install Win7

It doesn't matter how many partitions it is.

Based on the MBR format partition stipulates two types of partitions, the primary partition and the extended partition (logical partition), the main partition can have up to 4, the logical partition is built on the basis of the extended partition, that is to say, to establish a logical partition, the extended partition must be established first, and then the logical partition within the scope of the extended partition, the logical partition can have many logical partitions, and the extended partition is originally prepared for people with more than four partitions.

In addition, the computer boot boot is booted from the active primary partition on the hard disk, and the active primary partition on the hard disk based on the MBR partition can only have one, that is to say, suppose there are four primary partitions, and the fourth is activated, then boot from the fourth, then the bootmgr bootloader should be in this partition (the activated primary partition is the boot partition).

So, bootmgr has nothing to do with the partition there, the active primary partition is the most accurate answer.

XP and win7 dual system boot is actually very simple,Understand the principle of how you want to do it,The ordering of the menu lies in the setting in the BCD of the shouting town,It doesn't matter which partition the system is in。

As for XP+Win7, why use the bootloader bootmgr of vin7 and Vista instead of the bootloader NTLDR of XP, it depends on the bootloader in the MBR sector of the hard disk, this program can be used to change, go to this software in detail, Microsoft itself gave, you can find it in the installation disk.

As for your most realistic problem, it is actually very simple, suppose the hard disk has two or 3 4 primary partitions (only two are involved here, the rest are ignored), 32-bit is installed in the first primary partition, and 64-bit is installed in the second primary partition.

Then the correct approach should be, the first primary partition should be active, and the boot file should be in the active primary partition, that is, a primary partition actually has only one bootmgr and the entire boot folder.

Then the MBR bootloader sector of the hard disk should be written to the bootloader, which is Microsoft's Win7 Vista standard bootloader.

As for the configuration in the bcd file, you can use the bcdedit tool to modify it, but it is too cumbersome.

Just use it, this software can be found in the installed windows7, and it is also Microsoft's own.

The command line is as follows, the administrator rights run assuming the 32-bit system on the C drive and the 64-bit system on the D drive and the C drive as the active primary partition.

bcdboot c:\windows /s c: /l zh-cnbcdboot d:\windows /s c: /l zh-cn

That's it for these two lines.,As for the problem that both of the names in the menu are the same, you can use bcdedit to modify it, so I won't say much here.,If there's still a problem, add me by the way.。 It's good to type so many words. Definitely not copied - only five points. Ay.

Find a disk encryption software on the Internet and install it, install the win8 system disk encryption under the win7 system, and install the win7 system disk encryption under win8.

This can only be hidden manually, or with the help of third-party tools, Windows itself does not carry this function, Windows to Go is very similar to what you said.

You can try the following method, create a new ordinary user in the control panel, non-administrator, without administrator permissions, should not be able to access another system disk.
