Lets be more specific...i used cmd and run as admin, i executed cd /d C:\grub-2.02-for-windows (when i installed the grub from the website i installed to C:\) so we execute the command above and an we are at grub program directory.
Then we execute the command
grub-install.exe --boot-directory=G(letter of the boot partition on ssd we made, fill in your letter) --target=i386-pc //./PHYSICALDRIVE2
open the boot partition and recheck if all are done, then we get all the files of the usb's second partition if its not visible you can go to computer management and asign a letter it will reveiled, copy and paste all the file(zImage,rd,info,extra all 6 files...... except for the checksum.syno) to the root of the SSD boot partition, also get the grub configuration file from the grub directory of the usb's 1st partition edit it and change the vid(0x0000) and pid(0x0000) digits with those of your SSD and the MAC address of our motherboards lan, and copy and paste it in the grub directory of the SSD's boot partition.
then in bios ---> boot --> csm-- LEGACY ONLY
save and boot
worked just fine. thanx
