KALLT: I will try to do what you suggest. However, I'm not certain what you mean by cloning a partition to another one. Will you kindly explain, as if to an idiot? Thanks.
Got a tip for us?

Missing System Integrity Protection (SIP) / csrutil command

When you open Disk Utility, there is a function called Restore. With this you can copy an entire partition to another one, effectively cloning it. You can do this by selecting the target partition (your new El Capitan partition), selecting the Restore option, and then using your Yosemite partition as the source partition. The result is that you will have two identical partitions with Yosemite that you can use independently. The idea is that you just upgrade one partition to El Capitan and this process will (I presume) update your Recovery partition accordingly. You will end up with a correct setup and won’t lose your Yosemite installation. If you want to use a clean installation then you just have use the first method I mentioned in my previous post (create an El Capitan partition, launch the El Capitan installer application from your Yosemite partition and then point to the new partition as the target).
if Im not wrong, he could also "option+command+R" to access internet recovery hd, essentially updating the recovery hd. And from there, opening Terminal and entering "csrutil enable"
On 2nd thought, that my just update the same yosemite recovery hd....
Redheeler, I did hold down option, and, though there are two installations on my hard drive (Yosetime and El Cap), there is only one Recovery volume showing. It is stated to be Recovery 10.10.3. Into that (being compelled to do so), I entered a code (see my other reply of today). However, it did not disable SIP. Thanks for the suggestion.
KALLT: Because, after my request to you for further explanation and before you replied, it seemed to come to me what you must have meant. I reasoned that what you meant was to clone the CONTENTS of the Yosetime partition to the empty partition into which I intended to re-install El Cap. Essentially, I think that this is what you did mean, only the method I chose was different to the one you suggested (instead of Disk Utility, I used Carbon Copy Cloner). The result was a cloned installation of Yosetime in the El Cap partition. Then, as you indicated, having booted into the newly-copied Yosetime installation, I used the El Cap installer, in the Applications folder, to upgrade this installation to El Cap. I then booted into Recovery (Command-R, and later on, Restart-Option, as related to another correspondent). I entered the code csrutil disable, but the result was for Terminal to say command not found. Later, as stated already, I booted into Recovery by pressing Option on restarting, but found only Recovery 10.10.3. So, I was forced to choose that one. Into Terminal here, I entered the command suggested by Wolf (today), with no success. So, it seems that as regards disabling sip, and in spite of a lot of well-meaning advice, I am stumped! Please see my reply to Wolf. Thanks for your considerable input!
Wolf, thanks for what seemed to be the killer suggestion. However, I booted into the only Recovery partition available (see my latest reply to KALLT) and entered the code you suggested (I presume that the symbol in it IS an asterisk — what else could it be?). However, the response of Terminal was: Symbol not found_NSDictionary0_ There was a fair amount of other stuff, too, but it was too long to write down. The bottom line is that SIP has not been disabled. Thanks for your input.
CLOD-HOPPER,
Since you have the bootable El Capitan USB installer drive, boot from it, select Utilities > Terminal.
Run the csrutil disable command and look at the output. It should show that SIP has been disabled. At this point, issue the reboot command and select your El Capitan install.
The csrutil action will update the NVRAM with the appropriate settings that will apply to any subsequent re-starts on that machine. To re-enable SIP, use the same USB drive process and run csrutil enable.

Halleluiah, and let there be Te Deum (also, Te Dsemf)! What you suggested worked like a charm! SIP is now disabled, I am running the apps that I wanted to run, and all seems well, thanks to you. It would never have occurred to me to use Utilities > Terminal on my boot-up flash drive. Yet, that was the only place where an up-to-date Recovery Partition could be found. Once again, many, many thanks!
Sincerely, Clod-hopper
