vvcepheus7 Posted April 15, 2012 Share Posted April 15, 2012 Hi, I want make a ISO file from SSD force 3 120GB with windows 7 x64. When I format the disk, Windows 7 has create an adition partition of 100MB. For what is this 100mb partition? When I make a clone file I need copy this partition also? or it's only temporal cache? it's important copy for the backup?? If I don't do it the copy can I get errors? Thank you!

FoLmEr Posted April 15, 2012 Share Posted April 15, 2012 I believe it's used for the BitLocker feature in Windows7 Ultimate. Yes, go ahead and include the partition in your system image as well - there's no telling what will stop working if you don't (BitLocker, obviously, but what else).

vvcepheus7 Posted April 15, 2012 Author Share Posted April 15, 2012 thanks for reply. I not use bitlocker. I use ssd for install windows and programs. When I format with windows dvd, automatically create me 2 partitions. Link to comment Share on other sites More sharing options...
Toasted Posted April 16, 2012 Share Posted April 16, 2012 That would be the System Reserved Partition. You don't have to back it up as it should just re-create it self when it install Windows. Not sure if it's safe without it, Back it up in case there are issues. Link to comment Share on other sites More sharing options...
vvcepheus7 Posted April 18, 2012 Author Share Posted April 18, 2012 I understand that 100mb partition is to adapt the MBR partition table (old BIOS) to table new GUID (GPT) (extension of EFI). If you don't copy this partition will appear errors in the partition table and SO don't boot. SSDs apparently only work with GPT, not MBR.

Kind regards I am using a Corsair SSD (I forget which one) in the laptop system that I'm using right now to access the Corsair website. I once read about an approach that allows you to install Windows without that silly 100 MB partition, and I've used that approach so far on two Win 7 systems. Besides my laptop with the SSD, I also have a desktop with Windows on an HDD. And both of these systems use a standard BIOS, not an UEFI-type BIOS.

FoLmEr Posted April 19, 2012 Share Posted April 19, 2012 This guy describes how to install win7 without the 100mb partition being crated (I've tried and tested it as well). However, he also states that Ultimate users will lose the BitLocker functionality. Oh, and there is some other neat stuff in that post as well. Go nuts. EDIT: ooookay, I seem to have forgotten the link... And now I lost it. Figures. Link to comment Share on other sites More sharing options...
G50EED Posted April 19, 2012 Share Posted April 19, 2012 This link shows how to eliminate the 100MB partition from an existing Windows 7 installation (I have used this method myself). Note that you will then have the issue of properly aligning your new partition (i.e., 1MB starting offset): http://www.terabyteunlimited.com/kb/article.php?id=409 This link shows several means of avoiding having Windows create the 100MB partition in the first place (I have used the third method as I find it the easiest): http://www.mydigitallife.info/hack-to-remove-100-mb-system-reserved-partition-when-installing-windows-7/ Link to comment Share on other sites More sharing options...

And to answer a previous post's question, no problems whatsoever. I get the rationale for bitlocker, but I'm more likely to lose the USB drive that you need to decrypt the hard drive, than lose the laptop itself.

FoLmEr Posted April 23, 2012 Share Posted April 23, 2012 Why is the 100MB partition worth the effort of removing? Just curious. Link to comment Share on other sites More sharing options...
vvcepheus7 Posted April 23, 2012 Author Share Posted April 23, 2012 thank you for the information. But I prefer to keep the partition of 100MB for the moment, I think that do it all this it isn't very safe. Thanks! Link to comment Share on other sites More sharing options...
x509 Posted April 24, 2012 Share Posted April 24, 2012 Why is the 100MB partition worth the effort of removing? Just curious. Depending on the size of your drive, you might want more than four primary partitions, especially if you are multi-booting. Link to comment Share on other sites More sharing options...
