I am currently using RMPrepUSB to run Linux on a laptop which is not mine, it's from my employer.
The laptop came with Windows 7 Pro SP1 with 3 partitions - 1 hidden for boot manager, 1 for windows OS/applications and finally 1 for storing data.
Using a USB disk I can run Linux without having to touch the OS. With persistence turned on, I can run a Linux liveCD and make "permanent" changes to the OS which is something that everybody usually needs.
But using a 20MB/s USB pendisk it can be very sluggish. The persistence file can easily reach the 3 or 4 GB (updates, new apps, etc)...
Due to that, sometimes the experience can become a bit frustrating especially when you're dealing with a whole lot of small files that keep getting written/read to and from the USB drive.
Running it from the hdd would be easier and a whole lot faster, I'm sure. But doing that would be like installing Linux with Grub2 on dualboot, which is something that I am not much inclined to do because I wouldn't like my boss to find out that I have tweaked the computer.
Then I remembered that once I saw someone saying that we can install grub4dos by simply renaming grldr to ntldr and copying that to the boot partition of the hdd.
Would that work?
If so, what is the exact procedure?
Would that be:
- extract grub4dos to the boot partition of windows, using a linux livecd to be able to see that partition
- rename "ntldr" to "ntldr.original" and renaming "grldr" to "ntldr"
- what about the menu.lst? What entry would I need in order to boot the Windows OS?
Thanks in advance.
