Dear all,
I'm new of this mailing list. I apologize with you for mistakes i can do in my
question. Hoever I'll try to be as precise as possible.
I work with UBUNTU 16.04. GRUB 2.
1- After a PC restart (that is when the BIOS/UEFI has finished to inizialize
hardware periferals and give the
control to the GRUB) i'm interesting to know if GRUB implicitily (that
is without an explicit command from a user) can write to a drive
attached to a computer.
For example:
A- the PC is turn off
B- I put an usb stick in the usb port (no matter if usb is bootable or not);
you can suppose usb stick is formatted NTFS
C- I turn on the PC
QUESTION: after the BIOS finish its procedure and gives
the control to the GRUB, the GRUB can do, in some way that i ignore,
writing operations into the USB drive attached to the usb port.
The same question is for IDE and SATA drives (for example internal attached
Hard Disks different from the first containing the OS).
2- Moreover, can you tell me if there are case where the
GRUB communicates with the USB, IDE and SATA periferal drives during the
normal user activity.
For example when a USB stick is attached to a
running PC is possible that GRUB does writing operations ?
In both cases, can you briefly tell me the source files where these writing
operations are programmed in the source of GRUB ?
Detailed tips are welcome.
Thanks very much in advance.
Best Regards.
Vincenzo.
