I am confused a bit. My Windows7 Ultimate disc without SP1 which I'm ready to install in a few minutes on my fresh unfromatted SSD, does not have the fix to properly see 4k aligned disks and report as such. But will this install disc properly format my unformatted Samsung 840 SSD with proper 4k alignment? Some say yes, some say no and that I'd have to Shift-F10 during install and use diskpart. So which is it?
Another question, if I format my new SSD now with my current windows7 installation with 1 primary poartition to install win7 on. And then reboot with the SSD as single disk in system and boot from windows install-dvd. Will win7 installation still create that 100/200mb system reserved (extra) partition?
No because it will be already partitioned / formatted, but if you remove the single partition and re-create it, windows setup will make a small 100mb active partition plus one of the size of the rest of the ssd.
But I cannot format my new SSD on my system now, because my system does not have AHCI in the BIOS enebled, So practically I am forced to use the install dvd to format/partition mynew SSD with AHCI in the BIOS enabled, am I right?
Yes you can, ssds also work on ide mode, not optimal btw, and dont forget to enable ahci when you perform the reinstallation of windows.
