Aska Posted May 20, 2013 Share Posted May 20, 2013 I don't know if this is the right forum, in that case sorry First off, i set my HDD as following: 1° partition: 100mb windows partition 2° 50gb windows 3° 50gb MacOSX 4° 50gb MacOSX clone 5° 300gb NTFS for stuff My bootable partition was the 3°, and by chamaleon I was able to boot both windows or macosx. I uninstalled windows 8 and reinstalled windows 7, obviously it changed /boot flag to 1°. I used to use gparted to switch the flag back to 3°, but this time I tried with the diskpart and set 3° as active (aka /boot). Now the HDD isn't bootable anymore, BIOS doesn't detect it. I plugged the HDD in another Windows PC by USB. It doesn't work: i can't see no disk nowhere! Nor in Disk Manager. I tried to use gparted and plug the HDD AFTER gparted was running. I was able to see the disk and each partition as they used to be (that makes me think that there's any "physical" issue). I would like not to format the disk (however even though I would do it, i can't because it's not detected anywhere). What can I do? Can someone help me please? Thank you in advance.

3.14r2 Posted May 20, 2013 Share Posted May 20, 2013 Is it a Seagate drive by any chance? Namely 7200.10/11 Link to comment https://www.insanelymac.com/forum/topic/288652-bios-dont-detect-hdd/#findComment-1916501 Share on other sites More sharing options...
Aska Posted May 20, 2013 Author Share Posted May 20, 2013 Nop, it's a Maxtor. After many hours, I finally end up to switch to IDE mode from AHCI in the BIOS setup. Now I am able to boot Windows 7 again... half work is done. Since Mac OSX run only in AHCI mode, I enabled AHCI driver in the windows registry (I read some tutorial here and there on internet). Then I restarted the PC, changed back to AHCI in the BIOS, rebooted again and... nothing, auto-detection of SATA 1 is still in "guru meditation". That sounds wierd to me because I already had that setup before Windows 8 install (dual-boot Win7+Macosx x2, in AHCI mode). And plus, since the first bootloader is chamaleon and it starts from an HFS+ partition, why BIOS doesn't detect the disk and allows to boot the Mac straightly, bypassing Windows? IDE mode: disk detected. AHCI mode: disk undetected. Maybe I'm doing something wrong or I miss something...

3.14r2 Posted May 21, 2013 Share Posted May 21, 2013 Well, Maxtor was purchased by Seagate, so it's mostly the same. Google Maxtor BSY or Seagate BSY.
