win7 on bootcamp doesn't boot after upgrading Yosemite to 10.10.3

Thanks but I already checked that link.

My bootcamp partition is present, both restarting the mac with option key pressed and in Settings/Start Disk.

The solution posted to that thread solves my issue too?

I've executed the terminal "test" commands with this result

Doesn't seem to me that I have a lost partition like in the other thread.

Note that the unformatted partition at the end of the ssd disk was intentionally left blank for performance purposes.

tnx

So... I imagine that the sequence that apply to my case is this:

Sudo gdisk /dev/disk0 disk1

P (Print list of parts)

R (Recover)

H (chooses Hybrid)

Partitions numbers to be hybridized: 2 3 4 (only partition number 4 right?)

Y (Good for GRUB question)

N (part 2 boot flag)

N (part 3 boot flag)

Y (part 4 boot flag make NTFS bootable partition)

W (Write the new MBR)

Y (Yes! write the new MBR)

Reboot

Is that correct? Please help!

Quite hard to do but I succeded!

Seems to be a windows hardware issue. Have I to reinstall a fresh windows?
