My friend is in a serious trouble. Long story short, a few days before my
friend asked me to protect his one drive from unauthroized access as he was
giving his laptop to one of his friend for some kind of project work.
Yesterday, he came to me with laptop and where Windows XP was not getting
started. The error was "unmountable_boot_volume". I google on the same error
and found that the boot partition is got corruptted. He was lucky because his
data was on last drive i.e. E Drive. His hard disk was partitioned in 3
drives C,D, and E and all the stuff was on E drive which was being protected
by me removing all the users and groups from the Security tab.
He told me to reinstall Windows if the chances are less to recover the old
windows. Here the things starting messing up. Now, what happened is, when the
setup start what I notice is that all drive letter has changed. His E Drive
became C, D became E
and C became D by unknown reasons.
The problem is, if I try to install Windows on either the current D or E
drive it doesn't let me. In the end of file copy progress it stuck on NTLDR
and NTDETECT.com. Not because of bad CD or anything else. It is because of
the setup wants to write both files to C drive but the permissions are set to
None for each and every group.
Today, I was googling to know that how I can change the permissions. I tried
BARTPE to no avail. I tried CACLS and SUBINACL but no use. Maybe this is
because I don't know how to use the both commands properly. In BartPE Total
Commander it shows every drive contents except C drive. When I click on C
Drive it says "Drive not found" please choose another. Could be because of
Permissions.
The biggest problem is that it is a LAPTOP and I can't remove its hard disk
to plugin with another running PC. I also tried using BARTPE to create a
bootable USB PEN Drive. Everything works fine but when I try to boot from USB
Drive it says NTLDR
missing even it is there and being copied properly.
First thing, I would like to know is that what are default permissions on a
newly formatted NTFS partition within the Windows XP Setup? Secondly, can I
change the current permissions and ownership through CACLS and SUBINACL?
Can I change the C Drive Letter to something else and make another as C
Drive Active Partition? Which partition utility can help in this? Will
Partition Magic or any other utility will work because of Permission?
Let me make it more clear to you that the only problem is that the Windows
XP Setup is unable to copy NTLDR and NTDETECT.COM on C Drive just because of
permission. None group or user have any kind of control on that drive.
If something can be done through CACLS or SUBINACL then kindly write me the
complete command to take Ownership and Full Control on C Drive including all
Sub-Folders.
A quick response will highly be appreciated.
A VERY HAPPY CHRISTMAS TO ALL OF YOU!!!
