Dual Boot Win 7 /Ubuntu 12.04 problem , boots directly into windows

[PowerArjun]

Hey guys,

I installed ubuntu 12.04 on my ultrabook today but after restart, it boots directly into windows, my ultrabook has a 32gb ssd also, but i am not sure if that is the cause of all these problems.

After a few searches and running the command fdisk i got this :

Seems like ubuntu is on /dev/sdb5 ??

I also ran the boot info scrIpt ad here it is

Is there any way to reinstall Grub onto the correct location?

I am seeing a lot of these Intel Smart Response systems. They somehow use RAID and the Desktop installer does not include the RAID drivers. Most that have made it work disable the RAID. Some re-enable after Ubuntu, some install Ubuntu to SSD.

I do not have Intel SRT but saved these links:

Disable the RAID, for me it was using the Intel rapid management thingy and telling it to disable the acceleration or the use of the SSD. If you have a different system, just disable the RAID system then install Ubuntu. Once installed you can then re-enable it.

INTEL SMART RESPONSE & RAPID START TECHNOLOGIES

Hi, All,
Got a new mbd (Asus Z77), did research, here's some info on SSD caching and SRT, Intel's Smart Response Technology.

There are three "smart technologies" in Intel's 2012 Desktop Responsiveness Technology collection:



Smart Response Technology (SRT) - caches frequently used sectors of an HDD into a Solid State Drive (SSD).



Rapid [re-]Start Technology - caches DRAM in a Solid State Drive



Smart Connect Technology - keeps your Twitter, Facebook and email accounts up to date even if you let your PC go to sleep. Presumably the PC is constantly waking up to do this.

I won't discuss Smart Connect further, maybe you know more about it.

SRT technology achieves a logical drive which is like the physical hybrid drives from Seagate (e.g., the Seagate Momentus XT series). Rapid [re-]Start Technology enables you to turn on the SLEEP function in BIOS, but save the DRAM to an SSD. Wakeup is then nearly instant. DRAM & SSD are both blocks of solid-state memory, but DRAM is volatile so it's great to be able to cache it onto a solid-state drive. Once you can have your computer back in an instant with the shopping cart where you left it, we can let PCs shut down instead of making them wait for us. This saves power big-time.

CACHE FUNCTION
The cache system copies hard-disk drive sectors to the SSD cache drive, monitoring disk traffic to see which sectors are requested most often. In order to give the system Logical Block Address ("sector") access (underneath opsys-dependent, file-system-level access), the two drives have to be declared as a RAID array in the BIOS. Firmware in the Intel chipset (present since Sandy Bridge) must then be accessed to stipulate that this is not really a RAID array afterall. Rather, you have to specify that one drive is the SSD Cache and some other drive (or drives) are to be accelerated. It appears that a motherboard manufacturer-furnished DVD of drivers with an install wizard that runs only under Windows :-( has to be used to access the chipset firmware. Presumably the drivers interface an NTFS-based file system ("Explorer") and the drivers, not just the install wizard, run only under Windows. Good screen shots here (http://ubuntuforums.org/showthread.php?t=2038121): http://ubuntuforums.org/showthread.php?t=2038121 <rant> At this point, all of Linux Land has been told, to put it politely, to wait your turn for drivers (or,more bluntly, told to get lost). It is, in my humble and considered opinion, conspiratorial and gratuitous for Big Corporation Intel to arrange with Big Corporation Microsoft to place access to BIOS and chipset firmware in an operating system. This is a BIOS setup that belongs in the BIOS. </rant>

CACHE SIZES, PARTITIONS
The largest cache size (largest number of LBA blocks) that Intel's 2012-vintage SRT can keep track adds up to 64GB. If you have 4 fully populated DRAM slots x 8 GB, then Rapid [re-]Start needs an additional 32GB. Thus, the SSD cache drive should be at least 96GB. After designating cache and acceleration-target drives, the cache drive has to be partitioned with two separate partitions, one for SRT and another for Rapid[re-]Start. The only detailed instructions I've seen speak of creating a 96GB SRT partition and then shrinking it to 64GB to create the leftover 32GB space. Don't know what's going on here. We cannot create SRT and Rapid [re-]Start partitions directly because they have to be in the same volume or journal?

ONLY INTEL DRIVES FOR DESKTOP RESPONSIVENESS TECH
Since it is the chipset (Southbridge) firmware that creates the special LBA-level, semi-RAID hybrid logical drive from two (or more) physical ones, only SATA drives whose hard drive controller and RAID controller reside in the chipset can be used for SRT and Rapid [re-]Start. The current A77 chipset offers only two SATA III 6Gb/s drives, so those are your cache and accelerated drives. The other 4 Intel drives in this A77 chipset are only 3Gb/s, so there is no point in spreading the small 64GB SRT cache to them. In those 4 Intel chipset 3 Gb/s slots, one could build a RAID array with Seagate Momentus drives (750 GB, 32MB conventional buffer, 8GB SSD cache, notebook size). After 2 + 4 SATAs, it's all over for the A77 chipset and any more Intel Desktop Responsiveness Technologies. So you could look for a motherboard with an additional non-Intel HDC controller chip providing SATA III 6Gb/s sockets and run a fast 2-drive RAID 0 or 1 array there.

Conceptually, I like the idea of making the SSD a permanent part of the computer case, while the boot drives come and go as sizes change and (ugh) drives die. The SSD could die too of course, but there's nothing on it to save before you slip in the replacement -- it's just a cache.

[B]SSD CONCERNS
SSDs are less robust than many assume. Their memory depends on packets of electrons that can ebb away, faster at higher temps. A $700 enterprise SSD drive guarantees 10 years; no one's talking about the drives you and I typically use. And ordinary HDDs? Magnetic domains written on the sea floor by the planet's magnetic field reversals remained for 750 million years to track the oceans creation and establish the reality of continental drift. Meanwhile, Smart Response Technology (SRT) has no TRIM commands; writing won't be optimal if you have to erase first. And does the Intel firmware have load leveling? I do not know, but cache usage is so intense, it probably does not matter. Intel says to buy SSDs put together with more robust SLC (Single-Level Cell) chips, but Intel is the only supplier I've found so far that's making SLCs. I'll go with cheap MLCs & just replace the drive if it goes. It's only a cache.

I still want both Smart Response and Rapid [re-]Start technology in Ubuntu. Where's the best forum for Ubuntu community and developers to stay in touch?
Thanks everyone.

I want Ubuntu to host all my virtual machines, and I don't think I'll switch to Win7 as the host system just to get SRT and Rapid [re-]Start.
