Hi to everyone, I'm newly registered and after checking many posts for a possible solution to my problem, I find this community to be very nice and strong. I'm in a somehow desperate situation, so I hope that some of the great people around here, would take the time (which is precious for anyone) to offer me some help. I've browsed the past discussions and I've already started to learn a lot of new things, which I should have learned and apply them earlier before. I still didn't find a solution yet, only a person was disscusing about a similar situation, but with no real help for me. The situation goes like this: On one of my computers I am using TC with Hidden OS (Win 7 Ultimate) since many years ago. I know, many of you will wonder why I still use it and why Windows. Let's just say that I have some doubts about what happened after the sudden and very strange way of TC's project termination. I still remember the day I saw that very strange message posted on the TC homepage regarding the termination. Why Windows? I just need a full Windows enviroment too. Anyway, I have to use this setup and a few days ago I had to apply some Win updates for the Hidden OS. I've did this on other ocassions, without problems, but now after researching, I've seen examples and understood that the Win updates could actually cause big troubles for a TC enviroment. I now know this can be totally avoided with backups, backups and backups, but unfortunately I didn't do a full backup before applying the updates. Especially I'm sorry that I didn't know about sector by sector clone before. That I would have made before aplying any updates. So...after the restart and after entering the Hidden OS's password, I'm presented with the black screen Windows Boot Manager error Error 0xc000000f Info: The boot selection failed because a required device is inaccessible. There is no other option of entering the recovery mode, F8 option not working either, only this error. The thing is that the Decoy OS loads and works perfectly fine. Also, from the Decoy OS, I can mount the Hidden OS as a normal volume and have access to all of it's files. This means that Windows didn't play with the TC bootloader or the volume headers, right? It messed only with something inside the Hidden OS's files. I have the TC Rescue Disk and the first thing I did, was to restore the TC bootloader. After researching, it seems that one of the reasons for this error could be the BCD file being corrupted. I know the separate System Reserved partition (100 mb) holds that file in the "Boot" folder but I have noticed that on the Hidden OS partition there is a "Boot" folder too containing a BCD file. Isn't the Hidden OS using the same System Reserved partition for loading the BCD file? Or is it using this one instead? Further, I have compared the System Reserved partition's BCD file with the one found in the Hidden OS by opening them both with Visual BCD Editor and they are completely different in structure and size. The Hidden OS's BCD file lacks many settings found in the System Reserved partition's BCD file. I don't know if in my case this file could represent the problem, since the Decoy OS is loading, but maybe could be a hint. Maybe there could be some log files where I can find what is causing this trouble. I've already checked the Hidden OS's events logs by loading them up in the Decoy OS's Event Viewer, but I didn't notice anything important. Maybe someone more experienced and willing to help could find a solution. I have a strong feeling that this problem could be fixed with a little more knowledge. I really don't want to go down the road of wipe and clean install. I thank you all in advance!
