Multi booting with multiple SSD's

2 posts in this topic

Recommended Posts

I need 3 OS's to choose from: OSX, Win7 64bit, WinXP 32bit.

I want to have each on a separate SSD. I like the idea of 3 hard drives instead of partitions because of the aspect of control. But I don't hear of people doing this so I'm worried there's a good reason for that. I thought of installing a power switch on the power cable of each to control if they are powered up. That will be my way of selecting what OS I want. All my data will reside on a separate Sata hard drive. I'm worried that I won't be able to access all my data at times though. Now I use Win7 and XP and there seem to be conflicts at times: Sometimes some areas are not accessible. Not sure why. I need to understand this of course before going forward.


Because of virus/malware risks in downloading, I thought it best to use OS X for viewing downloaded content. For old applications and hardware that aren't Mac compatible I'll need Win XP 32bit. For newer apps/hardware that aren't Mac compatible Win7 64bit should be ideal.


I have no knowledge on bootloaders or whatever tells the system what to boot. I'd like to have whatever controls that on my separate Sata data drive of course. Or could I put that on all 3 hard drives?


Maybe I should just run 2 systems with a video switch: 1 for OS X and another for WinXP and Win7!


Opinions? Surely these issues arise in many people's systems.

Do some reasearch.


Install chameleon as your bootloader for osx and it will auto detect your windows partitions / drives, you'll be able to select which OS you want to boot in at startup.


OS's on separate hard drives is almost universally recomended as the easiest way to dual / triple boot.

      Hi guys, i'm trying to help a friend of mine trying to install osx(possibly high sierra) on his pc with the following specs: 
      Amd fx8350 
      Asrock 990fx extreme 3
      8gb of fury Kingston ddr3 ram(2x4)
      Radeon hd 7950
      128gb ssd( crucial m550)
      A couple of hdds I don't remember the brand(maybe a seagate barracuda and a dumb old disk for data)
      We tried to install it using the regular clover+high showers installer but we couldn't get it to reach the installer, then we tried osx-amd(don't know if i can talk about it there, sorry if i can't) and we still couldn't get to the installer.
      Is there a guide i can use to install osx in that machin, i tried to search in the forum but i couldn't find it.

      I am try to install High Sierra, as per #####
      I have have successfully booted from the install usb drive and have booted into "Install macOS High Sierra". I had to add a boot flag (-no_compat_check) to the clover bootloader in order for the usb stick to boot properly. Also, at first I couldn't see the SSD drive in disk utility, but I fixed that by asking disk utility to show all drives.

      Onto the current problem. I am having major issues trying to install High Sierra to a NVMe SSD. When I run "Install macOS High "Sierra" I get the following error:

      "The version of macOS installed on this mac is newer than the version you are trying to install. When a new update is available, you can install it from the Updates plane in the Mac App Store. If you want to reinstall macOS, please use macOS recovery."

      Also, It doesn't matter if the startup volume is formatted as APFS or HFS+.

      If I format the drive using GPARTED on linux, the installer just says the startup volume doesn't have journaling enable. If I then run disk utility and enable journaling on the startup volume, then go back to the installer, I get the aforementioned error msg.

      I have the following specs:

      Asus Prime X299 Deluxe.
      ADATA 512GB NVMe SSD.

      How do I fix this issue?

      In this video I first show the boot time of my system running on an OCZ Vertex 3 SSD APFS formatted and with TRIM enabled. As you can see the boot has a long pause at these "FIPSPOST_USER" stuff. The solution that always worked for me is to create a time machine backup and restore to disk. As you can see after the restoring that long pause is drastically reduced. The initial boot time is 45 seconds circa, after restoring is down to 22 seconds. TRIM is still enabled and disk is APFS.

      I want to use 7 drives on my ASUS X Hero MB.
      The MB supports up to 6 SATA drives, and also has 2 M.2 slots, so I thought it was possible to run at least 7 drives.
      Apparently, it isn´t that easy.
      I have a Samsung 850 EVO MZ-N5E500BW M.2 drive that I use as boot drive. It´s a SATA drive, and from what I can read, using a SATA drive in the M.2 slot will either disable one or two of the other SATA slots, depending on which type of M.2 setup you choose.
      So now I can only use a total of SIX slots in the machine for storage, which is a huge bummer, since I need the extra SSD drive.
        I can of course connect the extra SSD drive via an adapter and use an external USB port, but that´s a very impractical solution.   QUESTION:
      Can anyone tell me if it´s possible to somehow connect 7 drives to my ASUS X Hero MB?
      (Buying a new PCIE M.2 drive is not an option, since the M.2 drive I have is the boot drive, and I don´t wanna F around with cloning, replacing etc)   Thanks in advance!

      Salve, da ottobre del 2017 sto usando con soddisfazione un disco SSD Samsung 850 EVO MZ-75E500B.
      Ho abilitato il trim da terminale e credo che l'operazione sia andata con successo, infatti nel System profile vedo la voce supporto trim impostata a si.
      Ma con l'utility Disk Sensei di Cindori sembrerebbe che il trim sia disabilitato.
      Ora dopo 3 mesi di utilizzo rilevo che la vita residua del SSD è scesa al 99% per HWMonitor e forse anche per DiskTool, ma sembra sia al 100 per Disk Sensei.
      Non ho messo nessuna patch sul config (credo)
      Chi riesce a fare un po' di chiarezza ???
      Allego i vari screenshot e il config.
