Ubuntu Cappuccino Scuro
Hello,
As the title says it, I messed up my dual boot, esp. Win10's. I don't have a W10 Recovery CD and grabbed XP's instead, so that at the boot screen, the choice is XP or Xenial. Of course, "XP" won't boot!
I think I tried everything to fix it, Hiren's, UBCD, SysRescue, Live CD's,etc and Google.
What can be done about this? Anyone ever heard of such a stupid, embarrassing situation to be in? Thanks for reading.

Whatever you messed with it can only get worse if you use an old XP recovery media.
That said, what happened/happens exactly? You don't really say what is the problem...

Well I had W10 and Xenial's choices at boot. Having problems booting W10, I inserted XP install CD and got to r console and typed fixmbr/fixboot/exit.
This very "wise" operation seemed to have crushed a (no doubt) messed-up W10 boot and replaced it with XP's. 'Course this won't do.

Any factory installed Windows 8.x/10 is in UEFI mode so yes, by doing what you did ("fixmbr"), now you broke everything.Originally Posted by xyz
I really don't know what to suggest except reinstall everything??

With windows vista and later windows version, BCD is used as the bootloader which is totally different from the boot files used with Xp and earlier. I'm not sure why you thought and xp recovery CD would work? Why don't you have a windows 10 recovery CD? Very simple to create. It doesn't matter now as I expect you will need a full windows 10 installation DVD.

Thank you for paying attention to my problem.
No W10 access, no creating a recovery CD. Creating one using a Live CD would not be possible, I suppose. Wish I could go out and get a brand-new MBR.
My girlfriend uses Windows, so she's getting "nervous".

Indeed. Windows 10 recovery media is something you do with a functional OS. Some vendors like HP also have their own tools for that pre-installed. If you wait until you need it it will be too late.
A moot point anyway because now you need installation media (not recovery) to reinstall everything.
However, you may also ask in Windows forums; perhaps someone can suggest something I'm not aware of (because, you know, I don't use Windows and I couldn't care less for that OS); you don't need to nor should you mention the dual-boot as it has nothing to do with your problem with Windows (then and now) but is enough to flip some heads at those forums. And/or contact the vendor's customer support as they should be able to send you the full installation media (for a fee, of course).

of course "for free", as usual! And maybe you don't have a "Win-Addicted" girlfriend...and I don t want to throw her out of the "Windows" but I ll probably throw some money out ot the W......
Thanks anyways.

That fdisk does not work on gpt partitioned drives is not unusual. There is a new fdisk with 16.04 that does work with gpt.
Windows NTFS partitions have a backup PBR - partition boot sector. If you only ran XP repairs once, you may be able to restore a valid NTFS PBR.
PBR - partition boot sector NTFS must be Windows

As described, testdisk has an option to "Recover NTFS boot sector from its backup"
If Backup BS isn't available, choose RebuildBS, otherwise Windows repairs will not work
Instructions - see #12 for NTFS partition boot sector recovery
http://www.cgsecurity.org/wiki/TestDisk_Step_By_Step
You want to get to this screen:
http://www.cgsecurity.org/wiki/TestD...ector_recovery
select [Advanced] instead of [Analyse] and select [BackupBS]
Also check for /boot/grub in addition to /Boot
If UEFI, you boot from UEFI boot menu, not grub if Windows has issues. Windows typically needs chkdsk and you can only run that from Windows repair console. Best to have Windows repair flash drive.
I once used a Windows 7 repair flash drive to run chkdsk on my XP install. It was a better version of chkdsk as it repaired more things, but it converted my XP PBR to a Windows 7 PBR. In testdisk there also is a compare of PBR (dump) and the PBR had text saying ntldr in the XP backup and bootmgr in the Windows 7 version.
XP would not know about UEFI. And it may have installed a BIOS boot loader to MBR. But I do not think XP knows about gpt and may have totally corrupted things?
Of course the horse has left the barn, so it may be a bit late to close the barn door:

AFAIK this can only be done from a working Windows computer to create the bootable DVD/USB media.

Also it is free atm.
I have created a USB that will install Windows 10, 32-bit or 64-bit on one 8GB stick.
No license number is necessary when installing to a pre-installed computer because the license is stored in the 'nvram' chip.
