To Win7 Add Backup Start to Prevent Start-up Failure
|
When Windows 7 cannot startup, Microsoft's recommended rehabilitation method is to use Windows 7 installation cd-rom start system. But if on Windows 7 appear start-up failure, we don't have installation CD? We can for Windows 7 add backup startup, for a rainy day.
Understand Windows 7 startup
Conventional Windows 7 on start-up, firstly, and then NT60 boot record activation loading primary partition (usually disk C) bootmgr ", then the "read" C: BCD "on giving a startup menu, loading Windows 7 necessary boot file. So once "bootmgr" and "BCD" document error cannot start Windows 7. Windows 7 bring "repair computer" and mounted individually maintenance system (such as WinPE etc) and are with "BCD" document startup, so Windows startup malfunction, 7 routine maintenance way be useless.
To make Windows startup, should be 7 backup hard disk guide ways to change for GRUB launched (multilayer start-up), and then in other partition placed "bootmgr" and "BCD" documents, finally using "GRLDR" start "respectively different partitions bootmgr". With the safety of Windows and start the backup, later "c: bootmgr" cannot startup, we can also activate other zoning "bootmgr" to start Windows 7 (Windows 7 start the backup emergency steps.
Simple configuration: create backup startup
Backup start as long as copy "bootmgr" and "on" directory to other partition can. First run the registry editor, then find "HKEY_LOCAL_MACHINE BCD00000000", click on the menu bar "file - uninstall configuration unit", click on "yes".
Then will "c: bootmgr document" and "c: on" directory replication to D plate (" show all documents "and" show by system protection document "to copy). Due to the "bootmgr" to start the meeting after loading with directory "on the BCD" configuration files, so as to use "bcdtool" this software configuration "d: bootbcd" startup information can. In "bcdtool" click "startup configuration - open," open "d: BCD" on, and then on the left side window selects "Windows startup manager", "will change device" for "- = d:" can.
Tip: to facilitate the maintenance and reshipment system, still can be in E plate (or other unsystematic partition) add WinPE startup. Use virtual drives loading Windows 7 installation files, then put all copying files to E plate and in the "in" menu. Developed their startup configuration can.
Actual combat: using backup menu startup
Accomplish these operations, as long as the hard disk boot record to become "GRUB" and then configuration can be used. Firstly download used to direct the startup files (GRLDR and menu. Developed placed on C pan-gen directory. Then as an administrator operation bootice. Exe, click "master boot record", in the popup window select "GRUB for DOS 0.4.4". Finally, click "installation/configure", in the popup window select "permanent."
Tip: master boot record of change is more dangerous operation, the proposal to change before "backup MBR", the current guide record back to flash memory devices such as saving.
Now restart the system, computer started, the system will lead to GRUB will display system (selection menu), the default Windows startup is still seven, and original is no different. If the default startup malfunction, as long as the GRUB startup menu select "Windows 7 backup", it can load "d: bootmgr" continue to start Windows 7 system. If this backup menu still cannot start, still can be in GRUB menu options "start" (WinPE premise is already will Windows 7 installation files released in full to E dish), activate "E: bootmgr loading Windows 7 installation operation, enter WinPE system startup repair or armoured Windows 7. |
