the error message is
status: 0xc000000e
info: the boot selection failed because a required device is inaccessible.

can you help to strip out the code to run it standalone  ? ( I am not
a developer )


fo = open("/dev/sda1","r")
fo.seek(3)
str = fo.read(4)
print "Read String is |", str,"|"
fo.close()

after running it returns ->

Read String is | NTFS |
