will a repair erase files?

[iAsuno]

so i found out i can't install sp1 because bcd can't be opened and configuration registry database is corrupt. and the windows support guide tells me to:

 

1. Remove all floppy disks, CDs, and DVDs from your computer, and then restart your computer using the computer's power button.

2. Do one of the following:

   • If your computer has a single operating system installed, press and hold the F8 key as your computer restarts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you need to try again by waiting until the Windows logon prompt appears, and then shutting down and restarting your computer.

   • If your computer has more than one operating system, use the arrow keys to highlight the operating system you want to repair, and then press and hold F8.

3. On the Advanced Boot Options screen, use the arrow keys to highlight Repair your computer, and then press Enter. If prompted, select the Windows 7 installation to be repaired, and then click Next.

4. Select the language and keyboard input method, and then click Next.

5. Select the user name of an administrator account, type the password, and then click OK.

6. In the System Recovery Options dialog box, click Command Prompt.

7. Carefully type Bootrec /rebuildbcd and then press Enter.

8. Restart the computer, and try reinstalling SP1.

 

now, will it delete some files i have downloaded?

Like Mixzzz said. it will find the corrupt or infected files and fix them. and also restore the ones you may have lost. mind you they are fixing and restoring system files. if your worried than backing up can be your best friend

SP1 includes security, performance, and stability upgrades. also brings new improvements to features such as reliability when connecting to a HDMI audio device, printing using xps viewer, and restoring previous folders in windows explorer after restarting.

and thats it
