I recently bought a new laptop - the Lenovo Ideapad Y510P (http://shop.lenovo.com/us/en/laptops/ideapad/y-series/y510p/) that comes with Win8 pre-installed. Something unique about lenovo systems is their "recovery button". Basically it is a small button on the side of the laptop that I can push to bring the system back to factory settings. My *guess* is that lenovo does this with hidden partitions. From windows, I can see 2 partitions, but from the Administrative tools (under win8), I can see 6 partitions! (see this thread (http://forums.lenovo.com/t5/IdeaPad-Y-U-V-Z-and-P-series/ideapad-y510p-why-so-many-partitions/td-p/1241675) on the lenovo forums and these two (http://forums.lenovo.com/t5/image/serverpage/image-id/27339i37E9A02521943E2E/image-size/original?v=mpbl-1&px=-1) pics (http://forums.lenovo.com/t5/image/serverpage/image-id/27341i02D92E8964D7334F/image-size/original?v=mpbl-1&px=-1))
I want to dual-boot this system. Reading around, I found that I needed to disable the "secure boot" option from my BIOS. That was simple enough. From another system, I torrented Ubuntu 12.04.3 LTS 64-bit and made a bootable USB drive. Before using that on my laptop, from the win8 tools, I made an empty partition of about 230GB or so (to install ubuntu in). Then I booted off my USB drive and went though the usual procedure - though instead of selecting the "install alongside windows" option, I decided to manually select the partitions myself. Basically, I carved out about 10GB worth of swap space and allocated the remaining 220GB as root "/" directory. Ubuntu installed just fine and I was able to see GRUB come up during boot.
The problem was selecting windows from GRUB. It didn't work. An error message came up and then the system restarted. Sorry, but I do not remember what the error message was. I'm not exactly sure how, but by using Lenovo's "recovery button", I was able to boot back into windows. Some internet searching (from windows) told me to "repair my grub". Basically, the instructions told me to boot off the live-USB, install "boot repair" and select the default repair options there. I did that and at the end, it gave me the following URL,
http://paste.ubuntu.com/6136211/
The good news is that I can now boot into windows from grub. The bad news is that I have about 4 or 6 "windows" options to boot from in the grub menu and only the 3rd (or 4th?) one is relevant to me. The rest don't seem to do anything other than print some error message. Ubuntu works just fine. I'm worried about the following,
* Is my setup stable? As in; will it break again after an update ?
* How can I set windows as my default boot OS (instead of ubuntu) ?
* Finally - Is it possible to remove the redundant windows grub entries ?
Even though I *seem* to have things working, I'm really worried about stability. I've already got quarter of a mind to just go back to factory settings and forget about using ubuntu on this laptop.
Worried,
