In order to examine the security improvements of Windows 7, the Windows 7 RTM with version number 7600 was released, but there was a problem in the installation and the solution was posted for reference.
test machine was originally installed Windows XP system (SP3), not wanting to destroy the original partition structure, hang a piece of 30G hard drive is intended for installation of old Windows 7. This hard disk has only one partition, the format is NTFS, the drive letter set under XP is W, it is attached to the IDE port and is set as the slave disk.
worth mentioning that during installation, the plug serial number primary hard 1 hard to be identified, then the access is identified to 0 from the hard disk. After installing Windows 7 from the disk, everything works fine, but there is no XP in the boot menu. Before the installation, I checked it roughly. The 7700 version of Windows 7 can normally establish a multi-boot menu in the case of XP already in the system. Maybe I have encountered a situation of one hundred miles? It is estimated that the main and slave hard disk drive conflicts and other problems, it seems that everyone is generally on the existing hard disk to establish a partition for the second system, so few people encounter this situation.
based on Windows 7 and Vista are very close on the basic kernel, so take advantage of the program under bootsect.exe installation disk boot directory repair the boot sector, such as the implementation of "bootsect /nt52 ALL" command to reset the boot sector, but This will restore the boot menu to the state it was in before Windows 7 was installed, so that although XP can boot normally, it will not be able to enter Windows 7. So this method is not used, but based on the same assumptions, enter the Windows 7 system recovery interface, manually establish XP boot record.
Note that when using bootsect command, /nt52 option generally corresponds to Windows XP, and if the first system is not XP, but Vista or other systems, using this option may cause boot failure. In addition, the computer software and hardware application network (http://www.45it.com) reminds everyone that if NTLDR is not properly restored or damaged, you can try to use the MBR option to restore the master boot record at the same time, for example, for the above description. In the case, use the bootsect /nt52 C: /mbr command.
The specific operation method is:
Insert the Windows 7 installation CD into the CD-ROM drive. When entering the installation interface, click the link to enter the recovery interface (under the Install Now button), after entering Choose to enter the command line and then execute the following set of commands in sequence. OS
1. re-search in the hard disk bootrec /rebuildbcd
2. Create a boot record
bcdedit -create {ntldr} -D "Windows XP"
3. set the boot partition position
bcdedit -set {ntldr} device partition = D:
4. set the path boot file
< BR> bcedit -set {ntldr} path \ tldr
5. Set the display position of the boot record
bcedit -displayorder {ntldr} -addlast
After executing these commands After rebooting, you can see the boot option named "Windows XP" at boot time. After that, you can set which system priority to boot and how long the boot menu is displayed in Windows 7.
summarize, Windows 7 boot program used with Windows XP is completely different, it may be due to the conflict partition boot program covers Windows 7 XP, of course, we can also use the XP installation CD in the MBR Recovery program or the bootsect recovery program mentioned above to restore the boot program to XP version, but to keep the boot of the two operating systems, in the new version of the boot program for the old version of the Windows system to establish a boot record, is the most intuitive and The safest way.
