Bug in grub-mkconfig

[Michel]

From Michel Bizot mail:address@hidden somewhere in France
I am "junior" in Linux eventhough I am 77 year old, but I am almost expert in 
MS Windows.
Before sending you this mail I've tried many modifications in grub file, but 
unsuccessfully.

My configuration:
****************
Starting from BIOS
master 0 --> sda --> hd0 --> IDE 40Gb with Linux
master 2 --> sdg --> hd1 --> SATA 160Gb With Win XP
master 3 --> sdh --> hd2 --> SATA 160Gb with only DATA, not bootable
slave 2  --> sdi --> hd3 --> SATA 120Gb with Win Seven
****************
Disk by-uuid
15D8A01C886F9F69                     points to ../../sdh1
1894178394176294                     points to ../../sdi1
aba413da-672d-4dfa-ab06-c43303a488ab points to ../../sda1
d2005a76-5478-4e53-ab2d-c3ddb84cf56e points to ../../sda5

My comments
 Starting on Linux HDD, everything from grub menu is correct, except boot with 
Windows 7, which gives only : "reading file error, ctrl alt del to reboot".
My BIOS allows me to choose HDD for booting. Booting directly on Windows 7 HDD 
is normal.
grub.cfg has been built by grub-mkconfig without only one modification about 
duration of timeout.
I'm surprised that value of uuid is the same for Windows XP and Windows 7.
See below in grub extract.
Linux version is : Ubuntu, with Linux 2.6.35-24-generic-pae. Installed 
directly on HDD from Kubuntu CD 10.10
Attached my grub file is needed. 
Thank you for help you could give me and happy if I can give you opportunity 
to correct a bug, if any.
