9 OK, this is your problem:
10
11 The Dell partition is a FAT partition, in which Dell installs some recovery
12 utilities which we do not need for now.
13
14 The Windows Recovery partition is the NTFS boot partition for the MSWindows
15 OS, which itself resides in the (originally) 3rd large NTFS partition. In the
16 2nd partition you should find a ./Boot/BCD file, which is the MSWindows boot
17 manager. When you look at it with BCDedit you will find the kernel entry
18 which loads the OS from the 3rd partition. You will notice that the 3rd
19 partition is specified as a UUID and this is what is causing your problem. If
20 you change the 3rd partition either in size, or in position, you *must* obtain
21 its new UUID and edit the BCD file with this new string, before your system is
22 able to boot again.
