Sorry for incomplete message. Here is the full message:
At my job, I have a computer on which I can choose the OS so, I
installed my
lovely debian there (with "some" problems to make it booting
because of this
damned EFI ) but would prefer to keep windows in dual boot. Windows
partition is still there, but grub does not seems to be able to
notice it.
I can do all tasks on the Debian system, but I need to retrieve
some
informations which were configured on windows, and keeping a dual
boot seems
a not so bad idea anyway, so do someone have any idea about what to
do to
fix that problem?
Now some technical informations which could give (or not) some
hints to help
me:
The boot flag was on a NTFS partition sda1, 1GiB large.
Windows itself was on a NTFS partition sda2, more than 300GiB
large, but I
have resized it through Debian installer to 93GiB ( should be
enough for a
system which will almost never be used, even if the system's name
is windows
btw ). After simple resizing, it was still able to work.
There were 2 other partitions, one for windows recovery with NTFS,
and
another one for HP tools with fat32. I have removed both of them.
I now have a fat32 partition with EFI informations, mount point:
/boot/efi,
1.86GiB large on sda3, which is bootable.
I have lot of other partitions for Debian: /, /usr, /var, swap,
/tmp and
/home. Lot of GiB there.
The last partition is a FAT32 that I intend to keep to share data
between
windows and debian, on sd5, 61GiB large ( very large too, but
considering
the HD's size... I did not cared a lot about that ).
Have you checked that "/boot/efi/EFI/Microsoft\Boot\bootmgfw.efi"
exists? (It might be "Bootmgfw.efi".)
I'm not at work currently, but I'll take a look tomorrow. However, I
have already looked at what was in /boot and am pretty sure that I
have no file or directory with microsoft or windows in their name (
lowercase, uppercase and all kinds of mixes ). I'll check anew to be
sure anyway.
I only have a debian directory there:
--------------------
root@...-P07-2:/boot/efi/EFI# ls
debian
--------------------
Have you tried to switch to "bootmgfw.efi" through your firmware?
Which firmware?
Running "efibootmgr" should display all the values that your
firmware
knows about and the order in which they classified.
I'll install this tool and check what it gives tomorrow, thanks.
It was already installed, finally. Here is the output of the command:
--------------------
root@...-P07-2:/boot/efi/EFI# efibootmgr
BootCurrent: 0000
Timeout: 0 seconds
BootOrder: 0000,0001,0002,0003,0007,0008,0005,0006

Boot0007* IP4 Realtek PCIe GBE Family Controller
Boot0008* IP6 Realtek PCIe GBE Family Controller
--------------------
No mention of any windows'efi file anywere. I just rechecked on the
partition that I suspect to have it before my installation ( aka: sda1,
a 1GB large partition containing a folder named "Boot" at root ) and no
more luck. Sounds like all informations needed to boot windows lacks
now... I guess I'll have to try to rebuild them, if possible, or...
reinstall windows? I doubt I can: the restore files were on a partition
that I had to delete to be able to create mines ( despite any good
sense, they used the 4 primary partitions slots, when only one needed to
be bootable! I wonder how could those people could say they are computer
scientists, really! And it takes no more time to create secondary
partition than primary ones... grrr! But at least I know why I will
never go back to default installations for my personal uses. )...
Any idea?
