How boot environment fixes MBr and rebuild bcd in already installed pc

[jraju]

Hi,
 When your boot process is corrupted, you are given suggestion like using fixmbr, rebuildbcd etc to correct the error. I know that it is startup repair options.
Microsoft also gives the fixmbr and rebuildbcd commands as a workaround this problem . Microsoft says to use the install media or pre installed startup repairs to use those commands.
When we boot via installation media and access the repair the computer and go to command prompt, the directory it shows, is x:\source , which means that we are using the files in the installation media. By evoking these commands, how the boot folder in the reserved drive would get corrected. Please tell.
Sometimes, there may arise situation, when F8 on boot does not lilst Repair this computer. If the option is not there, microsoft says this is because there is no pre installed start up repairs files installed in the system. How could it be . Is it not a windows install process automatically at the time of installation?
So, does it not suggest that if you get the repair option in the advanced boot menu, then you are invoking these commands, or the system gets the command from the windows reserved partition?
So, my query above,
please give a detailed reply

.When the MBR is corrupt the machine will not boot so you would need to boot up with either install media or a System repair disk.

The fix bootrec or mbr cmds will then do the job.

Running Startup Repair three times would normally reinstate Repair your computer into the F8 boot options.

Hi, Thanks boggin.
But let me know, how correction made in x: , corrects the mbr in my c: reserved partition.
Thanks for the reply.
Boggins, Stilll all your emails are only received in my spam folder.
Is there any improvement .
Lately I heard that tim would fix it in a day or two.
what has happened

[Boggin]

It's the way MS has designed Windows and how it can be repaired.

My forum notifications are also going into my Spam folder but as I check the forum for replies, I don't rely on my emails for those.

Running Startup Repair three times would normally reinstate Repair your computer into the F8 boot options.

Should I do three times from the installation dvd, and should not choose the System Restore is that the procedure. please tell.
Your quote: it is the MS design
Is that the X: access the Reserved Partition of c: drive, hidden, and do the correction in the hard drive . Please tell.
Because, some websites recommend to use this command from C: by going to the c: from X: in recovery mode.
Boggins, regarding the spam matter, I am receiving the emails not from the tweaking.com server , but from via server.pg01.com .
Is that server anyway belongs to Shane.  Then , it is ok,
But if I mark the reply as not spam, it goes to the inbox.
But the next mail is received in spam folder. That is the concern

If you are going to come onto the forum then there's no need to check your emails.

You would need to boot up with install media to run a Startup Repair as it can only be accessed from Repair your computer.

The bootrec and fix mbr cmds would automatically execute on where the volume is installed.

Can you post a link to a website where it advises to change from x:sources to c:

Even when I run a sfc /scannow after booting up with install media, I enter the cmd from the default prompt but first run the cmd bcdedit |find "osdevice" and then I would use that partition letter instead of the X I have exampled in the following cmd -

sfc /scannow /offbootdir=X:\ /offwindir=X:\

For clarity that is a Pipe symbol before find and is the upper case of \

Hi, Thanks, Boggins.
The above tracert is for the owner of the site , of how it travels from my pc.
Thanks for the command and also for the tip , that it automatically finds the volume to activate the command.
What is the sfc scan offboot.
Do we need to scan the computer offline.
I hear that for the first time .
I usually use sfc on running windows only.
For a troubleshoot query, one answer was given as change to c: from X: , I will try to send the link. This is when i search the google for bootmgr is missing error I had .
I will try this command from recovery mode .
Please tell me about sfc offboot dir
thanks for all the tips

[Boggin]

The sfc offboot cmd is when you are repairing the volume using the install media.
