installation problem

[satimis]

Hi all,

Ubuntu 14.04 on USB
SSD1 - 1TB
SSD2 - 120G
Motherboard - ASUS M5A97 Le R20


Something very strange happened here. I tried to install Ubuntu on SSD1 first. Both SSDs are connected and detected by BIOS.

Booting up the PC

.....
......

This computer current has no detected operating system. What would you like to do?
(check) Erase disk and install Ubuntu
-> Continue

Select drive: [SCSI1(0,0,0)(sda - 1.0TB ATA TS1TSSD370]
(remark: other SSD also detected - SCSI1(0,0,0)(sdb - 128.0 GB ATA ADATA SX900)
-> Install Now

It pop back to following page again

This computer current has no detected operating system. What would you like to do?


I have tried an hour with the same result. Choosing SSD2 couldn't solve the problem.

This USB stick has been run to install Ubuntu 14.04 in multiple times without problem. Please help. Whether it is not allowed connecting 2 SSDs in the PC at the same time?

Is the installer giving an option to choose which drive to install Ubuntu on? Are you selecting sda = 1TB? If we do not make a selection then the installer has no choice but to ask again.

You may wish to avoid complications by disconnecting the drive that you do not want Ubuntu to be installed on. Just a thought.

Yes. 2 SSDs are available for selection. I have tried selecting both with the same result.

I have tried following arrangement;
1) Installed SSD2 taking up entire disc without LVM and without SSD1 connected. Then installed SSD1 with LVM selected also without SSD2 connected. Plug in SSD2. Both Ubuntu installed on SSD1 and SSD2 worked without problem. I can select either of them on BIOS to boot.

2) Unplug SSD1 and reinstall SSD2 with LVM selected. Then plug in SSD1 again. I could only boot SSD1 via BIOS but SSD2 is detected on BIOS. To boot SSD2 I must unplug SSD1

That is the present situation. Ubuntu on both SSDs are still working

Hi all,

Further to my late posting

I suspect whether it is the problem of the motherboard. This is a brand new PC built about one week. This is also the second new motherboard (ASUS M5A97 Le R20) replaced by Asus agent. The first motherboard could not boot PC.

Hard drives connection
SSD1 - connected to P1 SATA port
SSD2 - connected to P2 SATA port

I can install or reinstall Ubuntu without problem if only one SSD is connected. If connecting 2 SSDs the BIOS detects them. I couldn't select them to proceed as the situation mentioned on my original posting.

After installing Ubuntu on SSD separately and connencting them to the PC I could only boot SSD2 (SATA port P2). The BIOS detects both SSDs but always boot SSD2 automatically even selecting to boot SSD1 (SATA port P1). To boot SSD1 (SATA port P1) I must disconnect the cable of SSD2 (SATA port P2).

Besides the PC has been stopped working once. Another problem it beeped three times. I have to switch off the power and switch it on again to solve the problem.

I'll contact Asus agent here on Monday if I couldn't figure out the problem.

Hi all,

Performed following test:-

SSD1 (1TB) - SATA-1 port
SSD2 (120G) - SATA-2 port

1)
Disconnected SSD1. Booted PC with USB to install Ubuntu 14.04 desktop on SSD2. It went through without complaint. After reboot Ubuntu 14.04 is now running on the SSD2 without problem.

2)
Reconnected SSD1, still with SSD2 connected.

Booted PC with USB to install Ubuntu 14.04 desktop on SSD1. This time I was allowed to select drive (SSD1/SSD2).

Installation went through without complaint. After reboot Ubuntu 14.04 is now also running on the SSD1 without problem.

On BIOS I can select either SSD to boot without problem. Also I can mount SSD1/SSD2 to read its data after booting up the PC.

Conclusion:
I think the motherboard may not have problem. It was because it is NOT allowed having 2 LVMs on ONE PC.

Now a remaining side-problem;
I have another HDD (WD 1.5TB) on LVM, only about 1/2 space occupied. I couldn't mount it running either SSD. Is there any solution?

I want to moving its data to SSD1, wiping out this HDD and moving the data back. I'm prepared using this HDD for storage only.

Please help. Thanks

you should understand that all your issues are due to the fact that LVM is not used as it should to work properly

3 logical volume(s) in volume group "LVM1.5D" now active


Then on -> "Files" I can find HDD device. Data on HDD can be copied with drag-n-drop.

Start SSD1 and repeated above steps.

Now data can be moved amongst SSD1, SSD2 and HDD. I think it is NOT necessary making any change on the HDD.

Thanks
