Optiplex 755

I put in a larger hard drive and moved the old one to the 2nd slot. Plugged in the power which was already there. New Dell SATA cable from drive to socket marked SATA on the mother board. 2nd drive does not show up in BIOs. What am I missing.

Novice here, keep it simple, Please.

Thank you.

Why would I try the 4th port.  The 2nd drive shows in the SATA-2 port. There are only two drive slots.

I just typed a whole reply without being signed in and lost it.

You have 2 bays for HDD's.  That shouldn't be hangup for trying the SATA-3 port and seeing if both HDD's then show in the boot menu.  My suggestions are what I would try if having the same problem(s) on my 755 (currently for sale).

If a computer shop determined a SATA port isn't working, it would likely mean a new MB (motherboard) on a 12 yr. old PC.  Might be time for something newer if it keeps giving you trouble.

Try resetting the bios: Unplug the power cord. press and hold the power button for 10 sec or more. Remove the coin cell battery for about 10 min. Then put it back in. Plug power cord to the wall outlet. Start the computer and see if bios finds it.

Unless the battery has been recently replaced, it also might be a good time to pop in a new battery.

The 755 has what I consider "manual" BIOS.  It does not automatically detect new plug-ins.  Under Drives in BIOS, turn on your SATA ports that are otherwise off until you find your drive displayed in the BIOS screen. Any SATA ports not in use have to be off; otherwise, an error message will display at startup.

If by chance the above does not work, you might have to simply turn on all of your SATA ports, restart, then turn off the ones not in use.

I'm including a couple of screengrabs off of my previous 755.  They'll show once approved my a moderator.

SATA Off  1-26-19.jpg

I'm sure you know it's F2 to get into BIOS at startup.

MT = mini tower.  Though the size isn't always needed, somebody can't live without it.  But I will mention some smaller models have less sata ports.  Not that we can always assume, but didn't we already establish your 755 is an MT in your other posts?

Sounds like you have a dead port on your MB (motherboard).  Did you try any other drives in it, like a DVD drive?

If you use F12 at startup to get to the boot menu, I take it your drive doesn't show there either.

I don't know if a 755 can take 2 bootable HDD's.  But it still sounds like you have a dead sata port; especially if you tried it by itself without any other bootable drives plugged in.

You're welcome.  I just got done editing my post when your's popped in.

Definitely a good idea getting a cable with a 90 degree plug.

Hard to say from here if your current cable is bad.  I noticed SATA data cables are more durable than some audio wires.  Lower quality audio wires, accidentally pull on it or something and then it gets finicky or doesn't work at all.

the I had it plugged into the wrong socket. I probably should have guessed the white label went to the white socket. So now it shows up in bios, but not in the boot sequence.  Boot only capable of 3 choices?? and there is no floppy.

You said the drive shows in BIOS but not the Boot Menu.  Does it show in Boot Sequence in BIOS?

Something that came to mind is what version of BIOS do you have or when it was last updated?  A22 is the latest BIOS for the 755 as far as I know.  I don't know that updating BIOS for sure is a fix, but is commonly recommended before doing certain things on the computer.

Is it the Linux or Windows drive that the Boot Menu is not seeing?

"...white label goes into the white socket." - What white label were you referring to?

Please keep in mind your latest photos don't show yet. - In case they have answers.

I thought you were unable to get the drive in question to fully show up while plugged into the 3rd port (SATA-2), and not at all in the 2nd (SATA-1).

Since you marked your last post as solved, does that mean both drives are fully working?

Both drives work fine in SATA 0 slot. I don't believe there is a problem with either drives.

I now have the 1Tb drive in SATA 2 slot and it shows up in setup, but not in boot list.

Have not tried SATA 3 because I have space for only two drives in the computer.

Something that might be handy:  Optiplex 755 Tech Guide 

In the Boot Menu, where it shows "SATA Drive," if you hit enter on it, does it then show 2 drives (with both hooked up) or does it just go right to one of the SATA drives?

What made me think of it - Normally I've seen more detail, like a model # with the drive; whereas on your Boot Menu screen it just shows "SATA Drive."

Re: Optiplex 755 MT wants to DUAL BOOT the PC some way.

Jump to solution

DUAL booting, google that and read.. please..   (read then ask questions is best)

that is what you  long posts never said then said what is DUAL boot last.

Your BIOS is not a boot manager,at all (but you learned that forcing boots in BIOS can be done in A22)

GOOGLE Dual booting Windows and Linux, see the endless problems  on modern PC and UEFI issues.

Is that it ?  well only you know that, nobody can know  what you really want or expect, for sure. (not once told)

If you had newer PC, (CPU) with Hyper-v features you could run Linux as  image boot. from W7.(or W10)

Ok now you know how to force boots in BIOS, (the disablement of ports trick) so.., SOLVED THIS IS?

your MT has 5 SATA ports, plenty if one fails you can USE another, if you use   BIOS to do that. 

below is the MT motherboard with 5 SATA ports  that is why we ask (one reason) what case you have.

so if ONE FAILS we can switch to another, the PC wants to  boot on the blue slot, and as you learned it can be forced, in  tedious way.   ports can be enabled or disable and boot order too. IN BIOS... that is all you get..

755mt5.JPG

This is the full sized PC case, called MT  called MiniTower, the best of them all for future upgrades..

yes many pages show 2 HDD beyond scope of this document, yes..

the rules for using 2 drive to boot are also covered in windows and linux.

both,. w7, not W10.

they need to google to learn that.

the trick is the limits of W7, BCDEdit limits, for sure.  OR EasyBCD.exe (clean) click register.

google dual boot with 2 drives, finds them, in clear text easy search.

w7 only,. and linux and 2 HDD.  ezbcd is the most easy way and is 100% safe for malware.

FOUND IT here at MS.

 

After installing it, go to the Add/Remove Entries Tab >

Add Entry at the bottom.

From the drop-down Linux Tab select Grub, give it a meaningful name and point it to the appropriate drive. Click tab linux/bcd , for sure ONLY you know what linux you run and what boot loader it uses .Grub1,2 or Lilo. then what  linux drive, D:?  and then what partition GRUB resides.

 

dual booting W7 goes back to year 2007 .so NO LACK of examples ever on topic.

Never heard of Dual boot and therefore not what I want. I just want to be able to get to both drives from boot menu. I am assuming this is possible if everything works. However, the 2nd drive is not showing up in the boot menu so 2nd drive is inaccessible.

Also I DO NOT WANT TO USE WINDOWS 10, as I have said several times. I tried it and burned up my whole 3Gb data for the month jin about an hour, before I could figure out what to disconnect from the internet. Sent the computer back, the DVD was not working anyway. I hate W10, don't need to be connected every moment on my computer and don't want to send anything to the Cloud. 

I am keeping W7 to use the programs there and using Linux to get to internet so I don't have to worry about updates and security.

OK? whether you like that or not that is where I am.
